Mecha’thun Card Review

Boomsday Project is an expansion full of experimental, crazy cards, and this card is like the essence of an entire expansion. It’s insane. And I love it.

I honestly don’t think that it’s a good card at all, but it’s one of the most fun from the entire expansion. It will lead to hundreds of different theorycrafts, ways to make it work. Most likely none of them will really work, or at the very least none of them will work consistently and be better than already existing deck lists. The requirement to have nothing, literally NOTHING in your hand, board, deck etc. is already huge, but it gets even better. Since this is a Deathrattle, it’s vulnerable to any kind of Silence or Transform effects. Which means that you have ot trigger it right away yourself too. There aren’t many ways to do it. For example, Druid can play this + InnervateNaturalize. But it means that every single card was already drawn, no other minions are present on the field etc. You often need to plan for it multiple turns ahead. Like, if your opponent realizes what kind of deck you play, and you drop Spreading Plague, he might leave you with a single 1/5 Taunt and ignore it for the rest of the game, so you can never proc Mecha’thun.

Of course, since you play a combo that literally requires you to draw and play every single card in your deck, playing a regular combo seems better. The main downside of combo deck is that you might not have time to find/play your combo before you die. This card, while consistent, is literally the slowest combo you can have in the entire game. Most of the other combos are drawn and played with a few cards still left in your deck, few dead cards in your hand etc. This one literally can’t.

The closest “trigger” card for this we have right now is Cataclysm in slow Warlock – it might be an extra win condition once you enter fatigue, but those are still two dead cards in your hand, work only after you reach fatigue AND require this guy to stick for a turn. Otherwise opponent just Silences or straight up kills it while you still have cards in your hand and that’s the end of your combo. So yeah, it won’t work.

It is an absolutely terrible card, but at the same time one of the most fun and unique from the entire expansion. It won’t work in Standard, I’m pretty much sure of that. Maybe in Wild, especially many expansions from now, there will be some crazy ways to get rid of everything on the board, as well as in your hand/deck and it will be viable.

Card: 1/10 strength, 10/10 flavor

      you need: reckless experimenter, macha’thun, many draw & heal. maybe psychic scream.

      draw through your deck.
      as soon as possible reckless experimenter
      mecha’thun as soon as everything is gone. end-turn. win.

    I don’t think this card is absolutely horrible, if you draw through your deck asap and put this on the board your opponent has to either let you have a 10 attack minion hit him in the face each turn, or kill it and die. This creates a situation where they have to kill you quick, and you have guaranteed board presence which other big cards would love.

    That said, silence is really common. Hex and polymorth destroy this.

    Explore Un’Goro, Geist, Mecha’Thun Warrior

      I could see people experimenting with that. You just have to draw Mecha’thun and Geist so they don’t also become “Discover” cards, and hope you can either hit face, hit your opponents minions to kill your Mecha’thun, and hope they don’t have poly/silence, etc. I wish I could say this combo would be at least a bit easier, and that you could put in an execute as well, but unfortunately it’s only enemy minions :/

    Pull it off once then dust this garbage!

    July 30, 2018 at 11:48 pm

    Guys please… Do you know what does mean when it say no CARDS on your side of the BATTLEFIELD?? you cant have any CARD (not minion) on your side.. and if i remember right secrets and weapons are CARDS…dormant is CARD…quest is CARD… minion is CARD…

    • Birdmammal
      July 31, 2018 at 6:54 pm

      You sure? I’m pretty sure of Battlefield only consists of minions, NOT your weapons and secrets. it is a battlefield after all.

      • hah
        July 31, 2018 at 11:01 pm

        Im not 100% sure but there is bunch of effects that say: put a SECRET to the BATTLEFIELD. So it should count them because secrets are cards in the battlefield. also HEROES are in battlefield. not only minions…battlefield is where all actions are taken…if you wanna attack something its need to be in the battlefield (hero) xD it just my logic but we all know Blizzard and their (not)logic xD

        • KamaiTachi
          August 1, 2018 at 6:52 am

          Haha yea I don’t think weapons or secrets count. If they don’t then Blizzard may need to change the text a bit, maybe saying “Deathrattle: If you have no cards in your deck or hand, and no minions on your side of the battlefield, destroy the enemy hero.” Unfortunately, making the card text any longer than it already is may seem to be too much, and if it goes over 4 lines of text then it probably won’t look great

    July 30, 2018 at 5:03 pm

    What if you used Hemet? You made something like a ramp druid deck, with a bunch of low cost cards, and then you play hemet. You do this and eliminate your deck? Please let me know if i’m thinking of this wrong or of any flaws.

  11. DarkAc3
    July 30, 2018 at 3:46 pm

    Im thinking a Quest Mage with Elementals, draw deck fast, get quest done, play the 4 mana 4/5 Elemental that reduces cost of the Quest by 2. Play that 3 times (or 2 plus coin) to allow you to use the Quest Reward for 0 mana. Get cards down to Quest Reward (with or without coin), Mecha’thun and Pyroblast (or another removal but Pyro is just straightforward, could use Voodoo Doll, etc) Then play Mecha’thun, do Quest, no more cards in hand once you do Pyro, Doll, etc an… Win?

    Probs not but im gonna try this out xD

    Question, does having Aluneth equipped stop the deathrattle working of Mecha’thun?

    Could still work without Aluneth.

    Drop Pyro from deck and use Voodoo Doll instead with Book of Spectres if passing on Aluneth. Reduce spells basically and use draw from Book of Spectres, Elementals and searchers.

  12. Charlie Mitchell
    July 30, 2018 at 2:23 pm

    Why wouldn’t this work in the new tempo mage deck as a like a final push? In place of say a pyroblast. Aluneth, plus the new leg will empty decks wicked fast. Could be the hail mary once spell damage has been exhausted through control plays.

    • Grant
      July 30, 2018 at 9:34 pm

      With Aluneth youll die of fatigue before you can empty your hand.

    • hah
      July 30, 2018 at 11:34 pm

      and how will you destroy your weapon to have empty battlefield?? someone said that this only conut minions but NOO.. it count EVERY CARD on battlefield…(there is one card that say put one of each SECRET to THE BATTLEFIELD) so thats mean secrets, weapons, quests, minions, dormant counts as CARDS ON THE BATTLEFIELD….goshh xD

        Weapens are part of your hero once you play

    July 30, 2018 at 10:35 am

    I think people are overlooking this card. The combo is nearly impossible to pull off. But let’s forget about the combo as a core part of the card, and maybe as a bonus. I actually see this in Shaman decks. P

    How many times have you run a shudderwock deck, and the combo failed. But you’ve got enough value and healing from Hagatha that you’re still alive when you run out of cards. Boom, this gives you one last push.

    Well let’s have something similar in a Malygos deck. Your combo fails. But you’ve still got one Eureka left.

    Think about it with Eureka and Elektra on shaman. That’s two 10 x 10 on the board. Would work well as a ‘back up’. We’re also not sure how it will fit into mech decks.

    I think this will see play, but not for the combo win as the main win condition, but rather as a back up for other combo decks. In the end a 10/10 mech with deathrattle isn’t so bad.

    • Lucasato
      July 31, 2018 at 10:37 am

      Its very smart
      Seems useless spend a slot with a 10/10 cost 10,but its a card can give you +1 victory each 8-16 games (its what i estimate)

  14. JasonSan
    July 30, 2018 at 10:13 am

    I see three classes that can utilize this card:

    Rouge: Myra’s crystal + new deathrattle triggering weapon

    Hunter/Warlock (WILD): Hemet Jungle Hunter + Play Dead/Dark Pact (saved in hand and Thaurissan’ed)

    Druid: Naturalize

    Priest: Twilight’s call

    TBH Druid and Rouge are the contenders both being able to rush the combo with heavy draw, however if a priest has the Mech C’thun with two Loot Hoarders in the deck, then it is possible to have a heavy control setup. Alternatively, a strong big priest mix can be thrown in.

    • Killy
      July 30, 2018 at 10:26 am

      Your Hunter combo does not work, neither rouge. You have to kill your c’thun.

      • Birdmammal
        July 31, 2018 at 6:58 pm

        The Rogue combo should be able to work because it triggers the death rattle when the weapon is destroyed

        • Lachlan Mann
          August 1, 2018 at 3:52 am

          The issue is the deathrattle will trigger, search the board, detect mecha’thun on board and fail.

  15. onix
    July 30, 2018 at 9:58 am

    easy countered by skulking geist.
    one combo with this card instead is with shaman:
    eureka! then zap with crushing hand

  16. Montana
    July 30, 2018 at 8:16 am

    I wonder if there will be any Hemet jungle hunter combo with this card. Seems interesting. High hopes for this card.

  17. 1194Ching
    July 30, 2018 at 7:39 am

    Maybe a mechanic like this would work:

    Deathrattle: Summon 7 Mech-olytes.

    The idea of C’Thun not having acolytes is baffling.

    • Lucasato
      July 31, 2018 at 11:05 am

      The idea is a psycho cthum,he want you kill all your friends so he can help you
      I liked it very much,maybe my favorite card in entire game rigth now (the second one is uther of the ebon blade) xD

    • Birdmammal
      July 31, 2018 at 7:00 pm

      This c’thun is better it. needs no followers to help it.

  18. 1194Ching
    July 30, 2018 at 7:26 am

    This is hmm. I don’t know what to say.. I just wish they just revised the old mechanic to a new one. The old mechanic gave C’Thun his identity. This card is his shell.

  19. Smaragdptor
    July 30, 2018 at 7:00 am

    Could either work as a combo for Wild Warlock with Thaurissan+Drakkari Enchanter and Mecha’thun+Cataclysm, or within Druid hitting both Mecha’thun and Deathwing. Or maybe even Quest Druid, either by reducing both M’T and DW to (1) or at least one of them and saving an Innervate. Of course, all those option still require you to empty your deck completely before doing this, but that’s another thing, I guess.

    • Killy
      July 30, 2018 at 10:30 am

      Deathwing does not work, your board is not empty.

  20. KamaiTachi
    July 30, 2018 at 6:58 am

    I feel Rogue will be able to execute this the best. You can play Mecha’thun, Shadowstep it, and then Mecha’thun–>prep–>Assassinate the next turn. Vilespine won’t work because it’s on the board before the deathrattle triggers. The only real problem is drawing the combo pieces, but with Myra’s Unstable Element, that can become much less of a problem; still a risk as you may not draw everything you need, but by late game at 10 mana you’ll have drawn most of your deck already. Maybe throwing in Coldlights in wild along with Backstabs to kill them could work, assuming the enemy doesn’t take care of them and doesn’t play anything they can hit into. A spell hunter deck with play dead won’t work, because he will still be on the board. Trying to create copies will only prove to be a headache as you will have to remove all of the minions on the board, as well as any cards in your hand or deck that are minions being used for said copying. I’m not entirely sure about any other decks right now, so hopefully someone else can come up with a theory-crafted deck with me. Until then, with what we have now, I’ll be making a deck of my own, either when I get out of work or when I take my break. (Anyone willing to comment, it will be much easier to discuss over discord, as I won’t have to log back into the computer to check; I still will, just not very often.

          Mecha’thun shadowstep
          mecha’thun coin (hope for second, use ‘wanted’ on earlier turn, counterfeit if wild) voodoo then backstab

          • KamaiTachi
            August 1, 2018 at 6:42 am

            Unfortunately, you’d have to ensure that you have no CARDS in your hand, deck, or battlefield. I initially thought minions due to battlefield, and now understand that this combo is a lot harder to make work. I feel like playing this in maybe(?) some weird type of Zoolock with Mecha’thun into Cataclysm next turn is probably most of what we’ll see; sort of like a last resort against longer matches.

          • KamaiTachi
            August 1, 2018 at 6:53 am

            If anything you could throw a Hemet in there and just make sure he dies somewhere down the line

    July 30, 2018 at 6:26 am

    Love watching people go nuts with all this wild speculation and certainty about what the text exactly means.

    Here’s my (utterly unrealistic) plan for Mecha’thun Rogue:

    Combo Turn 1: Play Mecha’thun, hope that it survives to your next turn.

    Combo Turn 2: Play Sonya Shadowdancer, Voodoo Doll (targeting Mecha’thun), and something to kill Voodoo Doll (Backstab, Shiv, etc.) This will get you a 1-mana 1/1 copy of Mech’thun.

    Combo Turn 3+: Play Myra’s Unstable Element, clear your board, and empty your hand of all but the final 2 cards. When your board is ready, play your last 2 cards: 1-mana Mecha’thun followed by any cheap spell (Backstab, Shiv, etc.).

    • Kenchilada
      July 30, 2018 at 6:34 am

      In the Sonya part of your combo you can also Vilespine your Mecha’Thun. It might not be efficient at all to spend it there, but Vilespine is in every rogue deck and it happens to be flexible enough to kill your own minions too. If you’re running backstabs and shivs then it’s still probably the right call to use voodoo doll as well

  25. Pindead
    July 30, 2018 at 4:04 am

    Might be good in control priestwith double psychic scream and twilight call

    • Fluffy
      July 30, 2018 at 4:14 am

      Also comboes with coffin crusher. Won’t win the game, but dropping a vanilla 10-10 as deathrattle isn’t something to underestimate

  26. minti
    July 30, 2018 at 2:45 am

    😀 Like the pros say. I like the flavour of this card. It can give you an edge over those infinite decks that are incoming.
    The big problem i see is that this card is that the most infinite decks are the rogue ones. And with myras unstable element they can use this to kill you at turn 10 😀 considering that they can survive this. I like the factthat the valeera hero power may screw your effect :D. So if you are not countering Rogue. That this is a purely anti priest card :D. And priest are too low.
    On the other hand Warlock can burn your deck and leave you very unfortunate. But than again warlock can play around this card with demonic project. And with cards like bloodreaver gul’dan and probably azari already in the clear of demonic project this proves how OP it is.

    • minti
      July 30, 2018 at 2:49 am

      on the other hand it is a deathrattle so most people will be able to work around it. IF it was a end of turn effect it would be to OP. So at the end of the day its just some 10/10 extra mech boddy that your oponent has to deal in a mech deck.

    • Killy
      July 30, 2018 at 4:02 am

      How would rpgue kill you at 10? How should it work end of turn? Nothing here makes sense.

    This will be a new thing for warlock guys… How?


    Play Hemet 2 cards left in your deck might be thing… Warlock has the least cards revealed so far there could be a cheating a mech into the battlefield card… But best synergy is with “Cataclysm”

    • Killy

        July 30, 2018 at 3:34 am

        in wild: emparor… 9 mana mechtun + 1 mana bloodbloom + 4(3) hp cataclysm = GG

        for standard i dont know xD

        • Killy
          July 30, 2018 at 4:03 am

          Ok well that would work in wild after you draw your whole deck, I think in wild warlock has better combos than that.

    • minti
      July 30, 2018 at 2:47 am

      you kno wif you draw cataclysm and this card. You just negated your win condition. Since you must play all the cards in your hand and deck for this to win.

      • Killy
        July 30, 2018 at 4:19 am

    • Grant Thomas Miller
      July 30, 2018 at 9:29 am

      Yes, it won’t be killed instantly leaving you with a card that discards your hand, and a hero power that draws into a deck with no cards. Perfect.

      • Killy
        July 30, 2018 at 10:43 am

        Look at the combo “hah” suggested and think again.

  28. Vulpem96
    July 30, 2018 at 2:00 am

    How about Flobbidinous Floop? (Or However his name is spelled).
    You can play C’Thun and, as long as you don’t play any other minion, you can have a 4 mana 3/4 c’thun floop. That seems way easier to kill. And the combo with hemett still holds, since you’d only need to draw a single naturalize before dropping him onto the board for this to work.

  29. Guyopt
    July 30, 2018 at 1:21 am

    – Easy Exodia Druid.
    – Even Geist can’t stop the combo since you can activate this with Floop + Swipe.
    – this card will only be good in Druid. other classes can’t use this effectively.

    • Flashlight
      July 30, 2018 at 1:29 am

      Shadowstep, Prep + Assassinate. And Rogue can actually empty their deck and got a sort of Ice Block to stall and empty their hands. Sounds superior to Druid.

      • Guyopt
        July 30, 2018 at 1:32 am

        Will not work good in Rogue. rogue has other broken win condition and don’t need this cluncky win condition.

        • hah
          July 30, 2018 at 3:37 am

          yes and you will still have mechthun (minion) and weapon on board… does it looks like empty battlefield to you? you cant have anything on board (secret, weapon, minion, quest).

          • KamaiTachi
            July 30, 2018 at 6:47 am

            It only requires no minions on your side of the board. Technically, you are right; Mecha’thun will still be on the board, but that’s the only reason the rogue weapon won’t work. Flashlight was right from the beginning; you can play Mecha’thun, Shadowstep it, and then Mecha’thun–>prep–>Assassinate the next turn. Vilespine won’t work because it’s on the board before the deathrattle triggers. The only real problem is drawing the combo pieces, but with Myra’s Unstable Element, that can become much less of a problem. Maybe even throwing in Coldlights in wild along with backstabs to kill them, assuming the enemy doesn’t take care of them and doesn’t play anything they can hit into. I’m going to “re”post this comment towards the top so that anyone else who may have a better theory can craft one with me

    Paladin legendary spell you resummon this and other mechs.
    Pyromancer then coin to clear divine shields then equality, in wild you can even make it in one turn with Emperor Thaurissan or a coin from the Burgly Trogg from Gadgetzan.

    IF this ever finds its way into a druid deck, it would just be a (much) worse version of Malygos druid. Maly druid’s OTK effect is far easier to achieve (mainly ’cause you can achieve it faster) than the Mecha’thun combo, which you’ll only be able to play when you will have been able to draw out your whole deck, gotten rid of any remaining friendly minions on the board, emptied your hand except for Mecha’thun, innervate and naturalize, and most importantly having stayed alive. Trust me, playing such a game would be so exhausting, you wouldn’t want to play it ever again. ^^

  34. Slightly Miffed
    July 30, 2018 at 12:41 am

    I am by no means a deck builder so not sure HOW to make it work without some seriousntrial and error but thinking that something with quest druid would be interesting as it would reduce cost of card to 0. Would make triggering deathrattle possibly easier.
    Also in wild similar thing with emperor thaurisan (spelling?) Might make it possible with other classes. (Mage, frost bolt and the the card that I can’t remember name of that destroys frozen minions possibly for example)

    Still very conditional in surviving for this to be last card with the other bits you need though

  35. Wikator
    July 30, 2018 at 12:36 am

    This needs to be battlecry, not death rattle to be good. But maybe you can combine this with myras unstable Element and rogue newest weapon.

      July 30, 2018 at 12:39 am

      Sadly won’t work with deathrattle trigger cards, since there can’t be any minions on your battlefied either. It needs to die.

    July 30, 2018 at 12:28 am

    Hm. At first i read that it was only deck.
    Now that I realized it was hand and battlefield too and the shock is gone, I actually think this is well made.
    I doubt it’ll see a lot of play unless people find a consistent way to trigger it though.

  37. Kapy
    July 30, 2018 at 12:18 am

    This is actually quite good in Druid!
    As Druid going to fatigue is realistic with ultimate infestation and all the ramp. So having this one card is really strong in some match-ups and is not a too big investment.

    Obviously the opponent will always save it’s silence but you can save your ‘3/4 copy New legendary’ and naturalize for a save combo.

    • Hubriz
      July 30, 2018 at 1:50 am

      Druid going to fatigue is indeed realistic. emtying your hand and board at the same time while also killing your own 10/10 is not.

  38. GlosuuLang
    July 30, 2018 at 12:17 am

    Awesome card! Probably not viable competitively since the condition is so hard to proc. Sure, we have all had matches where we emptied all our resources and something like this would have won us the game. But it’s a dead card for a huge part of the game, or a cool-looking Faceless Behemoth if you don’t proc it. At least we will see it when summoned in Spiteful decks. Now, even though it’s probably a meme, I will always advocate for alternate win conditions, and this is one, albeit a clunky one. Competitively 1.5/5 stars, but flavor-wise and cool mechanic this is 5/5 stars.

    • GlosuuLang
      July 30, 2018 at 1:09 am

      Also, I don’t think this goes into Toggwaggle Druid. I’ve played a lot of that deck, and usually your second UI is a dead card until you switch decks. Since you have to dump your hand after you drew your deck in order to proc this, that sdcond UI will kill you due to fatigue damage. My Plan B in Toggwaggle Druid is and probably will continue to be Lorewalker Cho, to guarantee that I switch decks if Twig is broken.

  39. Tarquinius
    July 30, 2018 at 12:06 am

    Could be effective in a big warrior where you can dump this out of the the Boomship with Deathwing and something else, as they are as big as it gets.If the game plays out for long enough then you have a fun alternative win condition that you’ll only see once in a blue moon, but dropping Mecha’thun out of Dr Boom’s space ship is an awesome enough fantasy for me most the time I think. Plus once this has rush after playing the hero card it could be a decent play, especially if it lives to magnetise next turn.

    • hah
      July 29, 2018 at 11:59 pm

      actually dont know. the effect is this. destroy all minions…….discard your hand.. so you need to try it with deathwing dragonlord… i think it kills all minions then deathrattles trigger and then you discard your hand.. because its dont happen at the same time because you have (.) not (,) between effects. that is just my opinion but like i said, you need to try it with dw dragonlord.

  42. Coyote
    July 29, 2018 at 11:10 pm

    This card not only is weak to silence but also to minion generation such as furious ettin. But i actually think is pretty good for those control vs control matchups like control mage vs control warlock where both hands end up emptying.

    • Knifeandlantern
      July 30, 2018 at 12:03 am

      If you’re getting your opponent to tech in Furious Ettin, this card has already done its job.

        July 30, 2018 at 12:49 am

        Not only furious ettin, there is the warrior 2/6 that summon three 1/1, Leeroy Jenkins, The 5/8 with rush, the 1 cost 2/3 etc.

  45. Zulda
    July 29, 2018 at 10:36 pm

    There are three options to what deck you can put this in, Mill Rouge Running Myra’s Unstable element, a suicide-lock that can burn through deck and minions quickly, or togwaggle druid as a second-ish win condition. Definitely Run Deathwing and big taunts to protect C’Thun and then kill all the minions you have alive and get rid of your last cards. This Card Has Very Small Potential But Potential none -the-less

          July 30, 2018 at 2:14 am

          Could you further elaborate that? I’m curious how Ziliax and Star Aligner end up being major parts of an OTK Strategy, especially in warlock.

          • hah
            July 30, 2018 at 3:20 am

            you know…warlock has portals, emparor, wrathguard, treachery, doomsayer, bran bronzebeard, glinda, mech that reduce cost of other mechs by 1… should i tell you more? now you can use your own imagination how to pull out combo with mech with wrathguard and star aligner with wrathguard.

            emparor, next turn: glinda (5), mech (1), mech (0), mech mech mech, zilliax (0) on one of the mech 100 times if you can, wrathguard (2) treachery on wrathguard (2)… mech have rush with 40+attack and just attack wrathguard…10 mana x dmg.

            next one:
            emparor , next turn: portal (3) brann (0) 2x doomsayer (0) wrathguard (0) treachery (2) star aligner (4) soulfire (1) 10 mana 25 dmg…but if wrathguard stay on board after first battlecra that would be 28 dmg plus soulfire = 32 dmg, enough for otk. this one is meme but its otk 😀 same like 96 dmg heropower otk warlock. no need for competitive play but otk is otk xD

            sory for bad English

          • Hubriz
            July 30, 2018 at 4:46 am

            Alright, thanks for the explanation.
            The first one sounds like an interesting Combo. I tried comboing Glinda and Mechwarper with Skorp-O-Matics and Knife Juggler before, but I burnt the rope before the infinite knifes could kill my opponent.
            The Ziliax combo sounds like it doesn’t have the same problem, but I expect it to be pretty hard to pull of.

            And the Wrathguard one, albeit sounding like a pretty funny thing, it will work in about one of 20 games since it’s like a nine card combo which doesn’t even deal 30 face damage. You’d probably be better off playing malygos warlock. Still an interesting plan, even if not really competitive

    The very issue comes from the fact that it must not be your only win condition.
    It seems like it’s a card you want to pop out of a Sindragosa in a Big mage, rather than include it in a deck.

      Necrium Blade wouldn’t trigger Mecha’thun’s deathrattle since Mecha’thun would still be on your side of the battlefield.

  54. TNTOutburst
    July 29, 2018 at 9:25 pm

    Is it really that hard to make a druid that can survive till fatigue? Druids are good at control and cycling cards. Then all it is is a 3 card combo- mecha’thun+Innervate+Naturalize.

    • TNTOutburst
      July 29, 2018 at 9:44 pm

      Like seriously. I am possitive there are control druids that can survive until fatigue and playing their hand. Even decks that are not trying to do that sometimes do that

  55. Zucki
    July 29, 2018 at 9:23 pm

    It’s unfortunate that you can’t combo this with Rogue’s new deathrattle weapon, as that would leave Mecha’thun up and fail the empty board condition. I’m sure people will jump through hoops trying to pull this off, but it seems more like a Blood of the Ancient One than a Shudderwock at first glance.

  57. Soup And Salad
    July 29, 2018 at 9:09 pm

    I love the absurdity of Mecha’thun. It is a beautiful card.

    However, there are some control match-ups this could actually steal games in. Perhaps a Rogue playing Myra’s Unstable Element could use this as the win condition if all else fails. It’ll never happen, but when you’re going to lose, you might as well throw out that Hail Marry.

    Some people are bringing up silence, but something like this would be a tech choice AT BEST specifically for the long as crap control match-ups some Midrange decks would have to put up with. The control deck probably has already used any non-destructive removal already seeing as the whole point of a midrange deck is to play only the best cards.

    Mecha’thun is one of those bad legendary cards that are truly good enough that they just might work somewhere at sometime. It is one of the few legendary minions to truly earn the status of legendary along with Mimiron’s Head and probably a couple other’s I can’t think of at the moment.

  58. Arvin
    July 29, 2018 at 9:05 pm

    First of all, in order for this to trigger, this has to be your ONLY card left (so no N’zoth) on your EMPTY board AND it has to die.
    The card has too many conditions for a powerful effect.
    And to top it all off, it is susceptible to SILENCE, so you pretty much have to kill this the moment you play it, which is pretty difficult for its mana cost.

    Heh, pretty much just a meme card

    Does anyone realize this card wins you the game? Which means there is NOTHING else you need to think about except making this work. Your ENTIRE deck should be built around this card because it wins you the game immediately with NO risk. Yeah yeah aggro can overrun you, but that’s the case for all combo decks, and they don’t even GUARANTEE your win! Come on, some of you geniuses can and will make this work. It won’t win all games, but will 100% make you win everytime you pull it off.

        It is a lazy evaluation simply by saying that a deathrattle would be countered by silence and transformation effect. If that is the case every deathrattle won’t be playable at all.

        Not saying this card will be competitive but it seems rogue or priest will find a way to cheat out the minion and trigger the effect with combo.

    • 8BitBrain
      July 29, 2018 at 9:08 pm

      But you still have to survive for a LONG time, so you need tons of healing, taunts, and board clears.

  65. Orasha
    July 29, 2018 at 8:45 pm

    First off, I love this card’s name and design, even if it was what most people suspected. But this effect… is crazy! Even if it never works consistently, simply having alternate win conditions is fun for the game and promotes creative deckbuilding. Up until now, the only other alternate win condition is Exodia Paladin, and I suspect this will be just as hard, if not harder, to pull off.

    What classes can pull it off? Druid comes to mind first, since they have insane draw potential and can Innervate a Naturalize in order to kill Mecha’thun. I wouldn’t be surprised if this became an addition to Maly or Togwaggle decks, simply as an alternate way to win should plan A fail. Druid also has other tools to help them proc Mecha’thun in the same turn, like the Twig of the World Tree or cost reduction through Jungle Giants.

    Second is Warlock. Tapping aggressively burns through the deck, and you can use Cataclysm to discard your entire hard. Unfortunately, they would have to leave Mecha’thun around for a turn or try to rely on Alarm o’bot, neither of which is particularly great. In Wild, Warlock can reduce the cost of things with Emperor Thaurissan, allowing you to play Mecha’thun and then Bloodbloom into Cataclysm. on the next turn.

    Due to Myra’s Unstable Element, Rogue can proc the first condition fairly easily. You’ll probably have to Shadowstep it (which means you spend a turn doing nothing) and then blow it up with a bunch of Preparations, Eviscerates, and a backstab which is… pretty unlikely.

    • Buzz
      August 7, 2018 at 11:58 am

      What about prep + assassinate ? The mana cost also checks with a Shadowstepped Mecha’thun, and in this case, doing nothing for a turn is fine if you win in the next one, you just have to make sure you’re out of lethal and you win !

  66. Oh well
    July 29, 2018 at 8:43 pm

    Its still a 10/10 mech that will have rush with dr boom…not so bad even without the deathrattle. Maybe something will be revealed that will help this deathrattle trigger. I’m disappointed that this is all blizzard can come up with though.

      July 30, 2018 at 12:15 am

      The druid combo is way better. Play this, innervate naturalize. And druid can survive long enough to empty deck and hand, unlike rogue. Even with the legendary spell, your combo asks too many cards which makes it way too hard to achieve.

      • TeeChil
        July 30, 2018 at 12:31 am

        You’re right. I saw this, thought of the Myra spell and just spat out the first legit combo I could think of. But I’m actually starting to think that the Druid combo will be part of a high tier deck. Their defensive and draw tools are plentiful.

  77. GreenGuy
    July 29, 2018 at 8:12 pm

    I’m honestly not sure about this one. It’s very combo reliant, and it doesn’t look like an easy combo. Sure, you can empty your deck with Myra’s, but then you have to get rid of the other 9 cards in your hand. You can’t self destruct your Mecha’thun easily either, because the Assasinate in your hand is a card, and if your opponent kills Mecha’thun before you do, you lose.

    If it somehow is an easy combo, it’s easy Tier 1 deck. I really don’t see that though.

    • GreenGuy
      July 29, 2018 at 8:13 pm

    small nerf to spiteful decks, but this is so a rogue card with myra’s unstable element. Element on 5 or prepped earlier, on 9 the new weapon and attack and turn 10 play this and break the weapon. Druid can tutor this with psychmelon, but they don’t have much to activate it for sure. Miracle druid to thin their deck using biology project and stuff?

    • BriBriSlat
      July 29, 2018 at 8:09 pm

      Don’t think that will work, Mecha-C’Thun still on battlefield when weapon breaks, so deathrattle would have no effect. It has to be the last thing on your board to die when you have no deck or cards in hand left.

          Most of the 10 drops at this point are 8/8’s. We have Sea Giant, Emeriss, and MulchMuncher, as 8/8’s. There’s Ultrasaur as a 7/14. Mecha’thun as a 10/10. Then you have Deathwing and Tyrantus as 12/12’s. MulchMuncher and Mecha’thun have brought up the average results of Spiteful Summoner.

      Rogue weapon doesn’t work bc mecha’thun is still on the battlefield. Also druid can easily innervate into naturalize.

        Obviously I lost my brain in the last two seconds. Druid has literally all the ways to trigger it. Twig into deathwing, jungle giants, naturalize… And that deathrattle triggers don’t work.

          Deathwing won’t work because the board has to be empty

      Or just break necrium on the same turn as this

        How would necrium trigger the win? Seriously dude, think before you post.

          How could you go through the comments more than once and condescend to others who may have accidentally misunderstood what the card read using practically the exact same wording?

          Seriously dude. Stop and think about what these rather rude comments will accomplish before you post.

      Then deathwing is on the battlefield and you don’t trigger the deathrattle…

      Doesn’t work, you have Deathwing on board so deathrattle has no effect.

        Could work with naturalize, shield slam, etc.

        • Piterno
          July 29, 2018 at 8:25 pm

          But then Naturalize and Shield slam have to be your very last card in your hand and this has to survive a turn, unless you had a coin or innervate
