Malygos Druid Play Strategy
The biggest combo is to play Flobbidinous Floop and Faceless Manipulator the turn after you play Malygos and attack with the last charge of Twig of the World Tree, then play both copies of Swipe and Moonfire for 50 damage (this is assuming your origional Malygos doesn’t survive a turn, which it won’t most of the time. If it lives the damage goes up by 24 if there are no Taunts in the way). Unless you’re up against Warrior or Druid you’re unlikely to need all that, but it gives you some breathing room.
Players don’t like to give you a 20 mana turn so weapon removal is currently all over the place. With just Floop, one Swipe and both Moonfires you can still deal an easy 21 damage, or with 22 with Floop, Faceless and both Moonfires. You can expect to have you weapon removed much of the time. Faceless Manipulator’s main purpose is to raise the damage ceiling of the Malygos combo, but it can be played for tempo if your opponent has an appealing target on board.
VS Aggro Decks
Against aggro Malygos Druid just tries to get to the later stages of the game when the aggro deck starts to run out of steam. In these games the Malygos combo rarely ends up mattering, and combo pieces can be used as removal with fewer consiquences. You have to be pretty careful about whether or not to use Biology Project early on as ramping an aggro deck can be pretty detrimental. An example of when it would likely be safe to play early is if your opening hand is Biology Project, Wild Growth, Spreading Plague. This way you at least have an answer if your opponent goes wide with the extra mana you gave them. Depending on what you draw early it might not even be good to play it yet there. If your first draw is Nourish it’s a much safer play than if your first draw is Moonfire. Against aggro it’s probably best to wait until you have something you want to use that mana for to play your Biology Project.
Remember you can use Alexstrasza on yourself to heal to fifteen. While this version plans to play Malygos before comboing, against aggro the first Malygos will often stick, so if you’re presented with a safe opportunity to jam it onto the field it’s usually a good idea even if you don’t have Floop to follow it up (the Swipe next turn will clear most boards). Floop can be played either on curve or after an Arcane Tyrant to grab some tempo against aggro.
VS Control Decks
The Malygos combo is much more powerful in control matchups, so try as best you can to hold onto your damaging spells. You will often be tempted to waste a Moonfire to avoid overdrawing after an Ultimate Infestation, but if you’re in a matchup where you’ll need it it can be best just to risk it.
Against other combo decks like Shudderwock Shaman or the mirror, Naturalize is a great tool to ruin the opposing game-plan. Against Shudderwock Shaman it can be helpful to leave their Mana Tide Totem out to make them more susceptible to this.
As with aggro, you also need to be careful about playing Biology Project against control. If you have nothing to do with the extra mana you’re only giving your opponent more room to play their cards. Consider what cards your opponent might be able to play after a Biology Project (for example if they run The Lich King you might not want to play it into their turn six if you don’t have an answer) and hold off if you don’t need it.
Hold onto your Branching Paths if you can, this card can be an over-costed Savage Roar and that will win more games than you think. This isn’t to say you shouldn’t use them to draw if you have no better option but don’t toss them away for armor without a good reason. Considering your opponent will be removing your weapon most games Branching Paths is a good way to make up some of that damage.
Malygos Druid Mulligan Strategy & Guide
VS Fast Decks
Ramp is your best friend no matter what the matchup, so Wild Growth and sometimes Biology Project are the best to have. Lesser Jasper Spellstone is another really good card to have early if you can upgrade it. A single upgrade clears most early threats like Vicious Fledgling and Hench-Clan Thug. Swipe is good to keep, especially against Odd Paladin but even if the 1-damage aoe won’t matter much in the matchup as the 4-damage portion of the spell also clears most early threats like those listed above.
Spreading Plague is a strong keep against aggro as the wall of Taunts it provides can buy a lot of time. Malfurion the Pestilent can be good to keep if you have some ramp, but keeping a 7-mana card can be detrimental if you don’t have anything to do before your seventh turn.
VS Slow Decks
Mulligan heavily for Wild Growth, Biology Project and Nourish. There is so much draw in the deck that ramp is all that really matters early. If you have a Nourish and either Wild Growth or Biology Project already, keeping Arcane Tyrant can be good to establish some early tempo. Keeping Twig of the World Tree is often correct even though you might not play it on curve. The sooner you have it the less likely your opponent is to have drawn their ooze (but you can assume they have one in their deck somewhere) before you can attack with it enough times.
Malygos Druid Card Substitutions
Oaken Summons is a very powerful card and depending on how aggressive the post Boomsday Project meta is than it may be worth it to put the package back in. In this case Floop would likely have to go, but there’s been so many “highroll” decks this past year I wouldn’t be surprised if people played both and hoped for the best (although that sounds bad to me).
Floop's Glorious Gloop is interesting. Against the right deck you could play it, Swipe their board and gain 7 mana. This deck doesn’t generate many minions and the standard version of decks like this don’t have efficient board clears like Poison Seeds so I’d be surprised if it was worth it. When you Spreading Plague most of the minion trading happens on your opponents turn so I wouldn’t expect to get a lot of Gloop mana out of that. Again, depending on the meta it might be worth it.
Prince Taldaram is an option over Faceless Manipulator that would allow you to add hero power damage to your 20 mana combo, which from only that perspective is strictly better. To do this though you would have to remove Ferocious Howl, which I don’t think is worth it considering this deck already cuts Oaken Summons.
This deck has a more reliable Malygos combo, so I cut The Lich King from the list. There’s a good chance he’s still worth including.
Juicy Psychmelon has possibilities if you add Dreampetal Florist and maybe The Lich King. Four mana to go grab Malygos and something that can reduce his cost by 7 could be strong. That sounds super gimmicky and half the time you’ll draw Alexstrasza instead of Malygos.
If the meta is aggressive enough Wrath might find it’s way back into the deck. Two for deal three is pretty good against early aggro minions, and at worst the card is a 2-mana cycle.
