    2. coin and evolve patches after attack
    3.get sorcerers apprentice
    4. evolve your other 1 drop pirate 10 times
    5. get charge murloc wolfrider warrior charge

      Umm…. after you evolve the second time the sorcery apprentice goes away…
      But you can play a wisp and evolve that instead.

    Does anyone here play eternal card game because an identical card exists there. Like even the name. A coincidence can only go so far.

    Lorewalker Cho? Fill opponents hand? 😛

    They can’t really get rid of it to draw a new card, unless they cast something else first. Since u can always fill their hand again.

      You my friend… Are ON TO SOMETHING GREAT HERE!! Yes this will probably not be rellevant for any competetive decks… but for a MEME DECK!? BRILLIANT!

      1. Make sure your facing a aggro deck in wild.
      2. Make sure the board is clear and its turn 10 despite the opponent you are facing IS PLAYING AGGRO!!
      3. Emperor Thaurissan has to have discounted your lore walker cho atleast once as well as one of your unstable evolution so that you can play 10 of them in one turn!!
      4. Opponent has to have 0 cards (trust me im a doctor, hes playing aggro, 5% of the times he is ALWAYS guaranteed to have 0 cards in hand! ;^) )
      5. Now give him 10 unstable evolutions and watch him be unable to play them.
      6. ???
      7. Rank up from 25 to 24!

      0.002% of the times it works all the times!

    I wonder if they named this in part after unstable mutation from MTG.

    The Shaman meta is looking to be more geared towards aggro, where having key individual minions is less important than having a large, powerful board. Because of the way that the current meta looks, the AoE evolve spell is easily better in current Shaman decks than this one. However, this card could be really good under various conditions. If some sort of Mid-Range or Control Shaman list was looking to run an evolve spell for any reason, Unstable Evolution would be the choice pick because of the ability to re-roll bad evolutions and the ability to avoid evolving key minions that have persistent effects, such as taunts, deathrattles, and end of turn. Also, once evolve rotates out, this new card will only be the only evolving option.

    • JG

      Isn’t Evolve due to rotate out as soon as K&C comes in?

      • CD001
        November 29, 2017 at 6:37 am

        Nope – Old Gods rotates out with the first expansion of 2018 …

        As does MSG (bye bye Patches and Jades!) and Karazhan (Medivh, Arcane Giants, Firelands Portal and so on).

    November 28, 2017 at 6:44 pm

    Play Mage Quest, then Mana Bind, Shaman casts Unstable Evolution.
    Then proceed to complete quest before turn 10.
    Easy Win.

    “I got the best deals anywhere!”

    Seriously, we might start seeing Auctioneers show up to try and make a “Miracle Shaman” deck a thing with this guy.

    I think on its own, it isn’t that good. A 1 mana Evolve turned out to be great, but that morphed your whole board. Spending 1 mana per upgrade on a single minion doesn’t seem worth it. Granted, you can re-roll until you get something you like, but at the end of that, will you be satisfied with how much mana you spent on that deal? Maybe, but it seems too inconsistent for me. Evolve Shaman definitely doesn’t want it; while it CAN use it to upgrade its whole board, that’s really expensive. While Shaman DK is kinda the same way, the Shaman DK also gives you a much bigger upgrade. It just… strikes me as a gimmick that won’t work out. I’ll give it an extra point because the evolve decks have always surprised us with what they run, and another extra point because I think there might be something with Auctioneer that could be insane, but that’s me being really generous.

    This seems very underwhelming in Arena. Just not worth the investment of mana or card.

    Standard: 3/5
    Arena: 1/5

    • Piterno
      November 28, 2017 at 10:32 pm

      In arena, you can play a 4 drop on turn 4 and then turn 5 play this 5 times. On turn 5, you can have a 9 drop, which can be Soggoth, a big dragon, or Noggenfogger (lowroll) and you can also always stop at any point leading up to that if there’s a better minion at 7 or 8.

    • CD001
      November 29, 2017 at 6:46 am

      It’s more selective than Evolve though… you can keep the Flametongue Totem or Earth Elemental as they are while evolving the specific targets you want.

      Evolve is incredibly powerful but also kinda risky … this is less powerful but less risky. Seems like a reasonable trade off.

      I like the idea of Malygos Miracle Shaman though 😀

    Easy evolve into radiant elements or sorcerers apprentice and turn all your minions into 8-drops

    • Logic
      November 28, 2017 at 4:17 pm

      Why 8 if you can go 10?

      • Bad Logic
        November 28, 2017 at 4:30 pm

        bcuz 8 drops are better in stats and ongoing effects than 10 drops

      • David
        November 28, 2017 at 4:33 pm

        Because 8 drops are typically the best in the game.

      Shrieking geist actually didnt get any better, it already had a kill target in shaman, evolve. Itll get better when it can kill cards in other decks

    Now we just wait for the highlights of people rolling a sorcerer’s apprentice or radiant elemental and going off with every minion they can fit on board…..

  13. Vincent
    November 28, 2017 at 2:13 pm

    Evolve a minion to sorcerer apprentice or radiant elemental and you can evolve your minions to the max. Same in wild, combo with emperor thaurissan. This card is broken, nerf inc.

    • Vincent
      November 28, 2017 at 2:48 pm

      Oh infinite with thaurissan wont work, if it gets back to your hand it costs 1 again.

    November 28, 2017 at 12:59 pm

    I don’t get the “unstable” tag in the name. This gives you way more control and hence is more stable no? Haha nit picking but non the less super powerful card

    • Mitpaul
      November 28, 2017 at 1:50 pm

      I don’t think it has anything to with the cards mechanic and more realistically speaking. Imagine if you are a murloc raider who evolves into a kobold (kobold geomancer) only to evolve again into a bear (ironfur grizzly) and then a giant snow monster (chillwind yeti) and then… WHAT!? Now you are a goblin (Booty Bay Bodyguard)… and all of the sudden you are a GIANT boulderfist ogre only to transform once AGAIN into a war golem and… whats this?? THIS MURLOC HAS GONE ALL THE WAY INTO BECOME THE FIRE LORD RAGNAROS??

      Would you call whatever is causing this poor murloc all these random evolutions “stable”?

  15. Nick Lambert
    November 28, 2017 at 12:37 pm

    Seems like it might be a bit more balanced if it had Overload (1) on it. Evolve Shaman is already kind of a face-roll deck; this smooths out the edges with no consequences.

    • Cigares24
      November 29, 2017 at 2:22 am

      yeah it should have been 10 mana skip your turn

  16. BadBoomBoom
    November 28, 2017 at 12:30 pm

    Thats the most broken card i’ve seen in a while kkkkkkkk.
    Lets take arena as an example. Turn 5, u went first. U killed a minion with your 4 drop. Now, u play that, and again, and again, and u can have up to a 9 DROP?!?!? ON TURN 5?!?!?… I can already hear kripparian screaming at his computer.

    The Voraxx utimate combo enabler

    • Wut
      November 28, 2017 at 2:44 pm

      Toi bad the vorax only work once. After that its got evolved.

    • Ab00000
      November 28, 2017 at 4:06 pm

      Wrong this would just work once on the Voraxx or maybe not even I’m not sure it would just become something else

      • hihi
        November 28, 2017 at 6:31 pm

        Yeah the voraxx wont trigger. It states, “after you cast a spell on this minion,…”, which means voraxx checks for spell cast after the phase is over. After your spell phase is over, the voraxx will have turned into a random 5 drop, so the voraxx won’t exist anymore

        • sober667
          November 29, 2017 at 8:35 am

          Ye BUT if you evolve INTO vorax it should trigger 😀

          • Me
            November 29, 2017 at 9:35 am

            Nope cuz you didnt cast the spell on the vorax

    November 28, 2017 at 12:00 pm

    Yep, this solves the problem of horrible rerolls

  20. Draffyr
    November 28, 2017 at 11:58 am

    If this returns the spell to your hand and lets you recast it like it says in the release video, I’m wondering how it interacts with Gadgetzan Auctioneer. If each recast of the spell counts as another spell, I could see replacing Manatide with Auctioneer and making a miracle shaman out of this. No idea what all you would aim to draw, but if you have a minion on board already, you could Auctioneer and draw 4 cards in one turn while strengthening a minion, and that’s not bad at all. Even just totem, Auctioneer, make a three drop and draw two cards isn’t bad.

  21. Hotingdog
    November 28, 2017 at 11:57 am

    I wanna know the interactions with counterspell, does it come back to your hand?

    • Ertje
      November 28, 2017 at 12:09 pm

      Probably not. since the effect of the spell is cancelled, thus the effect that makes it return is also cancelled

  22. Ben
    November 28, 2017 at 11:51 am

    My fav shaman card in this set so far!

    • ab00000
      November 28, 2017 at 4:08 pm

      Yeah considering the other cards are just totem shaman and rune spear

  23. sober667
    November 28, 2017 at 11:47 am

    You have better controll over it than over regular evolve so i like it thou we need mana reduction on spels in shaman to have realy huge impackt but still if ou topdeck it late game u can bring up your totem up to 9 mana ( well better to 8 but u take what u get) with small chance to get untargetable minion wich will stop 😛 but i see solid card and insane arena cards u can in one turn repair aa bit all of your damaged minions seems realy strong for me

    • Brian Muir
      November 28, 2017 at 12:27 pm

      This card costs 1 mana, so if Shaman had any mana reduction for spell, you would just go infinite. That would be absurdly broken and would never happen.

      • Snail
        November 28, 2017 at 2:46 pm

        It might costed 0 on the first one. Then the next rever to normal.

  24. Emperor Thaurissan
    November 28, 2017 at 11:42 am

    Wonder what happens if you use me, then play this card. Does the cost reset when it returns or does it stay at zero?

    • cypher
      November 28, 2017 at 12:47 pm

      The cost will reset.

    • Nope
      November 28, 2017 at 1:02 pm

      Probably resets. It looks like Blizzard is trying to rebalance evolve, which is fine as long as shaman has other lines of play. It just hurts that other classes will get as much or even more value from this regardless of whether it’s even in your deck. It. This may also be an attempt to improve the class weapon. If that’s the intent then this card may be worse for the class than Moorabi. These are not strictly bad cards, but not likely to be useful without more support.

      It probably is.

    • Snail
      November 28, 2017 at 2:48 pm

      Turn 4 you cast costed 4 minion.

      Turn 5 you cast this until got a 9 costed minion.

      The impact is big.

      Might be a big shaman too with this one.

    • Blimey
      November 28, 2017 at 3:39 pm

      It’s not really a choice of one or the other, tho.
      If you’re evolve shaman you gonna play both, simple as that. And if you’re not evolve shaman you don’t care about either (although this one has some potential in some non-evolve lists where regular Evolve doesn’t make any sense at all).

    If you can somehow steal this card from a shaman and have a minion to reduce it cost, you can do some crazy stuff.

    Stealing with priest, having a radiant elemental you can fully upgrade a minion. And for the luls just add a questing adventurer/mana addict/yogg saron/lyra

    – You can use the spell as many times as you want in one turn.
    – At the end of your turn, the card is removed from your hand.

        shaman needs love?? highest winrate at blizzcon

        • Immolate
          November 28, 2017 at 11:33 am

          Are you trying to compare Shaman’s winrate at Blizzcon (where you can ban decks that are unfavored for your lineup) to casual and competitive players playing in ranked mode with one of the classes with the least amount of substantially different viable decks (the other being Hunter)? Token Shaman has been the only truly viable competitive Shaman deck since Un’Goro. Shaman needs some other viable archetypes and a slightly stronger power level to be able to compete against strong decks like Jade Druid, Highlander Priest, and Tempo Rogue. Especially when it loses the jade package and Evolve in April and a lot of the cards revealed so far for Shaman do not seem to be strong enough on the surface to carry Shaman to a higher status. This card can help promote a spell/value oriented Shaman deck, perhaps with Arcane Giants and the new spellstone that can summon copies of the giants.

          • Hotingdog

          Shaman has one of the weakest classic / basic sets and was amongst the worst classes in all metas up to TGT. It only became strong with LoE and then over the top when WotOG came out. Now with LoE gone and WotOG rotating out it is sinking back into bottom tier without playable cards. Last exp produced 1 class card for shaman that has seen real play.

          November 28, 2017 at 11:48 am

          Shaman it a single good card last expansion, once whispers and gadgetzan rotate out shaman will have nothing because of the garbage ungodly and knights cards they got, shaman will likely be a non existent class in April if they don’t print good cards and the totem cards are garbage, shaman currently needs more love than hunter.

        • ARandomWizard
          November 28, 2017 at 11:55 am

    What does “Reapeatable this turn” mean?

    • Immolate
      November 28, 2017 at 11:12 am

      It uses all your mana to cast these on one minion?
      You can play two copies of this on the same minion?
      It adds another copy of this to your hand?

      I have no clue. Evident, please help. Although I think it was released by a Chinese YouTube channel, so we might not know for awhile.

      Even without the repeatable, its not that bad of a card.

      • Crapcrack
        November 28, 2017 at 11:19 am

          “It’s not that bad of a card.”

          Doesn’t mean it’s good either :). Although when you compare it to Shaman’s DK hero power, it’s a little better. I try to be optimistic about new cards, especially when we haven’t seen all of them yet. I’m sorry if you were offended by my statement.

    • Ertje
      November 28, 2017 at 12:14 pm

      When you play it, an almost identical card will return to your hand, that looks the same says the same, but will disappear after the turn ends, to make clear that it doesn’t have unlimited uses for the duration of the entire game
