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 + Innervate + Naturalize. 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
what if you are able to zilliax magnetize on this card? think about it OMG…
I LOVE OFF-META!
This doesn’t get bud from card that “give your c’thun +x/+x wherever it is.” Right?
i can hear its saying “i said no more fatigue game!!’
This card Will be the king of meme deck
The god of wild and Standar
Like the other meme king, Just good in wild
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 :/
Hello memey, I’m definitely going to try to make this card work
Me too. Cataclysm seems like an option, or maybe myra…
Are we sure cataclysm works? someone said that cataclysm would destroy before discarding
Hmm, maybe… i guess we’ll just have to wait and see
Play the discounting mech twice while this is in your hand. When the time comes, it’s this, bloodbloom, cataclysm.
Pull it off once then dust this garbage!
No no no no no no no no no you do not stop there my friend, you have to go beyond. Druid. Rogue. Warrior. Whatever class it is make this card work in it! Let the memes begin!
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…
You sure? I’m pretty sure of Battlefield only consists of minions, NOT your weapons and secrets. it is a battlefield after all.
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
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
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.
YOu can naturalise it in Druid
that actually sounds like a genius idea
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.
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.
With Aluneth youll die of fatigue before you can empty your hand.
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
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.
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)
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)
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.
Your Hunter combo does not work, neither rouge. You have to kill your c’thun.
The Rogue combo should be able to work because it triggers the death rattle when the weapon is destroyed
The issue is the deathrattle will trigger, search the board, detect mecha’thun on board and fail.
easy countered by skulking geist.
one combo with this card instead is with shaman:
eureka! then zap with crushing hand
Doesn’t work your hand is not empty.
You’d need Ancestor’s Call, so it plays it from your hand.
Do I see a wild combo here?
I wonder if there will be any Hemet jungle hunter combo with this card. Seems interesting. High hopes for this card.
Maybe a mechanic like this would work:
Deathrattle: Summon 7 Mech-olytes.
The idea of C’Thun not having acolytes is baffling.
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
This c’thun is better it. needs no followers to help it.
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.
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.
Deathwing does not work, your board is not empty.
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. Feel free to add me at KamaiTachi#8618)
Also, thanks to Flashlight, as he was the one who I first saw had the idea (I’m sure others did as well, but I’m bouncing this off of his comment with more detail)
Assassinate says “Destroy an ENEMY minion” so you can’t kill your own.
Well, I forgot about that. Makes that plan pretty void then XD back to square one I presume
mecha’thun coin (hope for second, use ‘wanted’ on earlier turn, counterfeit if wild) voodoo then backstab
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.
If anything you could throw a Hemet in there and just make sure he dies somewhere down the line
This look like a fun card. But if a pro player find a consistent way to kill the opponent whit him , will gain tons of ate.This rings my some kind of wild bell, but i cannot still focus….
Should be changed to “at the start of your turn…”
Then it might be viable but not OP.
THE BIG CHEESE STANDS ALONE!!!!!!
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.).
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
Good point, and worth including as a redundancy.
Might be good in control priestwith double psychic scream and twilight call
Also comboes with coffin crusher. Won’t win the game, but dropping a vanilla 10-10 as deathrattle isn’t something to underestimate
😀 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.
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.
How would rpgue kill you at 10? How should it work end of turn? Nothing here makes sense.
I am sitting here and reading all the posts discussing Rouge and Druid… Lol
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”
How exactly are you gonna play your 14 mana combo?
in wild: emparor… 9 mana mechtun + 1 mana bloodbloom + 4(3) hp cataclysm = GG
for standard i dont know xD
Ok well that would work in wild after you draw your whole deck, I think in wild warlock has better combos than that.
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.
Your “combo” is playing this and then cataclysm you don’t negate anything..
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.
Look at the combo “hah” suggested and think again.
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.
– 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.
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.
Will not work good in Rogue. rogue has other broken win condition and don’t need this cluncky win condition.
or… you know, the new rouge weapon
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).
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
EDIT: Assassinate works on enemy minions, not your own. Mistakes were made
does it say minions or CARDS??? secret is a card on the battlefield…weapon is CARD on the battlefield…minion is A card ON THE BATTLEFIELD…
Actually, Swipe can’t activate.. so Geist is a problem..
Swipe can’t target your own minions.
No but MULCH can so still works
This ensures fatigue decks don’t become meta, which is nice since those decks are boring, not as boring as freeze mages, but close.
An edge-case question for an edge-case card:
Is my battlefield considered to be clear if I have Sherazin or The Darkness out but still in their dormant forms?
Yes, I am fairly sure your battlefield would be considered empty. Unless Blizzard consistency.
NO. dormant card is a CARD ON THE BATTLEFIELD SO ITS NOT EMPTY… same with weapons, secrets, questy,
also here in description of the card says this: LITERALY NOTHING ON THE BOARD, DECK, HAND etc.
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. ^^
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
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.
Sadly won’t work with deathrattle trigger cards, since there can’t be any minions on your battlefied either. It needs to die.
rouge deathrattle card is a weapon and a spell there is no rouge minions like that
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.
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.
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.
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.
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.
