Malygos Druid Deck List Guide – Boomsday – September 2018

This Malygos Druid deck guide will teach you ins-and-outs of this popular deck from the The Boomsday Project expansion! Our guide will show you how to mulligan, pilot, and substitute cards for this archetype!

Introduction to Malygos Druid

Malygos decks in general try to take advantage of his +5 Spell Damage to destroy their opponents in one explosive turn. Druid has been a popular class for the archetype historically due to their excellent ramp and draw tools, but also because of the 0-mana damaging spell Moonfire. All these strengths have been enhanced over time, but in the past year Druid has received something new: a vast bounty of survival tools (various armor-gain and Spreading Plague). With all the draw and armor-gain Druid now has (often on the same card) playing a slow combo style of deck in this class has never been easier. Malygos Druid also gained Twig of the World Tree last year, allowing it to play both copies of Swipe the turn Malygos comes into play.

With The Boomsday Project Malygos Druid gets a versatile new combo piece: Flobbidinous Floop (say that five times fast). Floop is always a 3/4 for 4-mana copy of the last minion you played, even if the last minion was the turn before. Malygos can now be played from hand with or without Twig of the World Tree. If the opponent removes it there is still a 3/4 Malygos in hand at a comfortable 4 mana, ready to Swipe/double Moonfire for 21 damage. Floop comes at a price though, costing 4 mana means players can’t efficiently include Oaken Summons in the deck.

Malygos Druid Play Strategy

In a perfect world, this deck survives until it can attack four times with Twig of the World Tree, then attacks the fifth time after playing Malygos. This gives the player ten extra mana to work with, which ideally would be used to play either Flobbidinous Floop, one Swipe and both Moonfires for 36 damage, or both Swipes and Moonfires for 30 damage. 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. You can expect to have you weapon removed much of the time.

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. Similarly, on a turn you could play Ultimate Infestation you don’t have to be as concerned about overdrawing something important. If you really need to remove something and have no other way to do it it’s probably the right thing to do.

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 is more likely to stick. 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 because comboing him is not as necessary in these matchups.

Giggling Inventor is an amazing neutral anti-aggro tool, so amazing that aggro decks have started to run Blood Knight. Think about how devastating a 9/9 Blood Knight would be before playing Giggling Inventor because you will run into them. Opposing Odd Rogue, Deathrattle Hunter and Token Shaman are all likely to be using Inventors themselves which you can punish with Spreading Plague or often Mind Control Tech.

Branching Paths is a very important card in aggro matchups, and not just because of the armor. The wider your opponent’s board the more value you get with Spreading Plague, and Branching Paths turns all those 1/5 scarabs into Sen'jin Shieldmastas. This can either clear your opponent’s board or present lethal damage, so consider your options when playing this card earlier on.

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. You can play Alexstrasza the turn you break Twig of the World Tree and then Malygos double Moonfire after, but in general it’s better to Alex the turn before and then Malygos/Floop/Swipe on the Twig turn.

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.

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, especially now that Giggling Inventor is in the list. You can expect most opposing control decks to be playing Inventors themselves, so keep that in mind before you toss away a Spreading Plague just to get it out of your hand.

This deck plays some extra minions, partially just because Giggling Inventor is such a good card, but also because all the control Warlock decks are playing double Demonic Project. You play around this card just like you used to play around Dirty Rat. Hold back minions that don’t matter so when your opponent plays Demonic Project they won’t always hit an important combo piece. Sometimes Demonic project gets you a minion you might like to play, but these decks are now also running Sacrificial Pact to get extra value out of their Demonic Projects. If their life total doesn’t matter much it can be right to go for it, but if you’re getting close to lethal damage it’s better not to.

Malygos Druid Mulligan Strategy & Guide

VS Fast Decks

Ramp is your best friend no matter what the matchup, so Wild Growth should be kept every time. 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 ThugSwipe is good to keep (especially against Odd Paladin) 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. Giggling Inventor is also good to have against aggro, but if you’re encountering Blood Knight a lot it might not be worth keeping.

VS Slow Decks

Mulligan heavily for Wild Growth and Nourish. There is so much draw in the deck that ramp is all that really matters early. If you have a Nourish and Wild Growth 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

Innervate would have been a staple in this deck back when it provided two mana, but the current one mana version still has its uses. It can help you curve out a little easier, but it also provides another card to toss after you would Ultimate Infestation to 10 cards in hand (and allows yous you to play Lesser Jasper Spellstone or Naturalize in the same turn).

Biology Project ended up not being the game-breaking monster a lot of people thought it would be, turns out giving your opponent two mana is too much of a drawback too much of the time. Still, it can be handy if you’re willing to be extra smart about when you play it. If you want to try a version that includes Biology Project, play it when it would act as an Innervate or when it allows you to play something big the turn following, and not when it would allow your opponent to play something you don’t have an answer for.

If you run into other Twig of the World Tree decks or decks with Skull of the Man'ari a lot then weapon removal can be a big advantage, especially now that decks like these have cut Oaken Summons. Gluttonous Ooze gives a little armor which can be handy in aggro matchups, but Acidic Swamp Ooze costs less and is thus easier to fit into your curve. Harrison Jones might be overkill, this deck has a lot of draw already and struggles to empty its hand when it needs to.

Oaken Summons is a very powerful card and depending on how aggressive the meta is then 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 and Faceless Manipulator are decent options to add extra damage potential to your combo turn. Taldaram probably not as much because you would have to cut Ferocious Howl, but in general they’re not often necessary. Most scenarios where you can pull off your Malygos combo you’ll be doing more damage than you need anyway.

This deck has a more reliable Malygos combo, so many players have cut The Lich King from the list. He can still be worth including for the alternate win condition or just if you’re missing Alexstrasza.

There are versions of this deck finding success with Dreampetal Florist. Florist can be strong by reducing Malygos’ mana cost to 2, or 0 sometimes if it manages to hang around for a turn. While that is both strong and doable against control, it struggles not to be dead-weight against aggro. While this was a risk well worth the reward initially, this is a combo-heavy meta and controlling Warlock decks have started including two copies of Demonic Project in their decks. When you play Florist against a Control Warlock deck you’re asking to get Project’d the turn following. If you do decide to play a Dreampetal Florist version of this deck, you could use that knowledge to your advantage and play it out when you don’t have Malygos in hand hoping your opponent will waste their Demonic Projects with no chance of success.

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.

    This is the first netdeck i´ve deemed fun enough to build. And oh boy is it fun, decision making from start to end.
    I have made an alteration to fit the perceived meta: 1 keeper of the grove over 1 mind control tech for those lovely blood knights and magnetic aggro decks.
    I am also considering cutting a giggler for the second ferocious howl to empower the jasper stones.

    How are you supposed to win against the warrios who are just armouring up 24/7

      Its a bad matchup. If you can full combo with twig it’s winnable but it’s hard. You could try the version that also runs Togwaggle/Aviana and beat ’em that way.

    I don’t have twig. Any good replacements?

      Lich King if you have it, Ferocious Howl if not.

      Not recently, the only quest druid Ive played was the charged devilsaur/cube/deathwing one. Hows yours working out?

    I don’t think that Alexstraza is needed right now in this new meta. Alexstraza most of the time will be in your hand a dead card, if you add Lich King to your deck you can get an extra damage card or an extra board removal, it also has Taunt that can stop aggro for a turn or two. One thing that i don’t understand is why do you have to run two biology projects, as in the guide says it’s pretty bad if your opponent takes advantage of it more than you so maybe wrath is better than biology project at least one copy of Wrath should be in the deck it can give you an advantage against the super aggressive Healock and maybe take one biology project off the deck

    I understand the idea behind this version of the deck but it seems a bit cluncky. Because nowadays everbody runs weapon removals and it is nearly impossible to pull out the 20 mana combo. Personally, i like the juicy psychmelon and dreampedal florist combo. Especially with floop. Because you play your dreampedal florist it hits your malygos then you play your flooped florist and hope it hits your manipulator and then you could pull a 50 dmg combo off without using twig(double swipe, double moonfire) which is probably the only way to beat control warrior or heavy armor gaining druid decks. Twig doesn’t work in this meta.
