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

    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.

    Does it works if you have minions and cards in your hand and then you play cataclism? That’d be an interesting tech addition to some warlock decks out there

    • 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.

    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.

        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.

    like. it’s cute. and I love it for the lolz. but at the end of the day we have wiz bang and also this guy…… along with some very sub par class legends they are kind of pushing it on silly legends and unplayabe ones… I think a druid deck can all in this and do alright but after first few times of it. seems like it would get old quick

    Is Deathwing on the stack when it’s battlecry triggers or still in your hand?

  7. 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

            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

    Demo-mill+MechaC’thun + Cataclysm ?
    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.

    • Soup And Salad
      July 29, 2018 at 9:40 PM

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

  16. 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

  17. 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.

  18. Lori

  19. 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.

  20. 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.

      • Feitonghofei
        July 29, 2018 at 9:06 PM

        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.

  27. 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 !

  28. 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.

    – Shadowstep
    [Next turn]
    – Mecha’thun
    – Backstab

    – (2) Eviscerate

    • George Badea
      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.

  39. 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.

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

          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
