Demon Zoo Warlock Overview & Strategy
First thing I want to address is the lack of Prince Keleseth. One of the main reasons why Zoo decided to go for the Keleseth in the first place was lack of good 2-drops. When Vulgar Homunculus was introduced back in the Kobolds & Catacombs, players have tried out the non-Keleseth version, because Homunculus is a really strong 2-drop. It turned out that it still wasn’t worth it and everyone played Keleseth again. Right now, another good 2-drop is getting released – Void Analyst. It shares the Keleseth’s stats and has a similar effect. While it works only on the minions in your hand (and only Demons), it also means that you can run two copies, as well as Homunculus. Is it good enough to drop the Keleseth? I honestly doubt it – I think that the Keleseth version will still be better. But we won’t know until we test it out.
First new card I want to focus on is The Soularium. I believe that this Legendary spell is the best thing that has happened to Zoo in a while. Drawing 3 cards for 1 mana is a completely broken effect. While you obviously won’t use it consistently, often you will play only 2, sometimes even 1, but it’s still not that bad. The card has so many uses. You can drop it if you’re looking for a specific mana play (e.g. if it’s Turn 4 and you don’t have anything to do, you can play this and hope to get a 3-drop, or possibly a 1-drop + a 2-drop), a specific card (like Doomguard or Soulfire to close out the game), or simply want more resources in the mid/late game. Zoo Warlock runs out of cards really quickly, but at the same time, it doesn’t really care about losing any specific card – they’re all disposable and Zoo can win the game without any of them. In the late game, situations in which you end up drawing a 1-drop, and then tapping into another 1-drop are simply worst – you aren’t really putting any pressure on the board. Those are the moments in which The Soularium will shine – you will be able to draw 3 extra cards and possibly even play all of them, making a big push on the board.
Besides The Soularium, this build runs a bunch of different new cards. Void Analyst is one of them. This card will be mostly useful in the early/mid game, when your hand size is still relevant. 16 of the minions in your deck are Demons (2 of them are Void Analysts), which means that there is a significant chance to have at least 2-3 of them in the hand in the early/mid game, and buffing them can be pretty significant in a Zoo deck. The most notable buff target would be Doubling Imp, which “double-dips” on the buffs – getting out 2x 3/3 minion on Turn 3 is really great in Zoo. But it can get even better – Soul Infusion is another card the deck plays. 1 mana for a +2/+2 buff is already pretty good (you can make some early game tempo pushes – like buffing Vulgar Homunculus to 4/6), but it works even better if you land it on Doubling Imp or Saronite Chain Gang. In case of those two, it becomes 1 mana +4/+4, which might be good enough to win some games by putting lots of pressure (you know how good getting down a T4 Chain Gang buffed by Keleseth feels like – this is going to be even better). You want to manipulate your hand in a way so those will get the buffs most often, but a more expensive card might be stuck on the left side of your hand sometimes. Putting it on most of the minions isn’t bad – e.g. buffing Doomguard to 7/9. Probably the worst target would be Hooked Reaver, but it won’t happen that often.
Now, onto the self-damage package. Outside of buffs, this deck is full of self-damage effects, as well as some cards that benefit from them. The good old Hooked Reaver might finally be good in Zoo Warlock thanks to the Crystallizer. Trading 5 health to 5 Armor will make activating Hooked Reavers in the mid game way easier. Having just a few health points too much was pretty common, and Crystallizer can get you down from 20 to 15. 4 mana 7/7 would obviously be strong, and it will be sometimes possible to drop it on the curve now. The second card which benefits from self-damage is a new Nethersoul Buster. It starts as a mere 1/5 for 3, a card you wouldn’t really want to play. But just one self-damage card, or even Life Tap, and it’s AT least a 3 mana 3/5, something you wouldn’t mind playing in Zoo. However, it can go even higher – combo it with Crystallizer and it becomes a 3 mana 6/5. In the mid/late game, getting it to 8-9 attack will be pretty common. It will be really useful in slower matchups – if they don’t immediately kill it, you kill them.
On top of that, the deck runs pretty standard Zoo cards, some of which were played ever since the first versions of the deck a few years ago. Like I’ve mentioned already, it’s hard to say whether this version will be better than a Keleseth version, or the Heal Zoo version. For example, card slike Nethersoul Buster or Hooked Reaver have potential to be really powerful, but are a bit risky to play. Playing them with their base stats really suck, but on the other hand, they’re completely overpowered when activated. So you need to be able to activate them consistently. It’s hard to say whether you will be able to without actually playing around with them, but that’s exactly what I will do early in the expansion. After all, best decks in the history of Hearthstone wouldn’t be created without experimentation – even seeing Heal Zoo for the first time, I thought that it just can’t work and it’s a meme deck, so I was obviously surprised when it was all over the ladder a few days later.
Demon Zoo Warlock Mulligan Guide
Since it’s just a theorycrafting and there are no statistics to back it up, I’ll just post some general guidelines for early playtesting rather than a full mulligan guide.
- Zoo is pretty straightforward when it comes to mulligan. You always want your 1-drops, especially Flame Imp and Kobold Librarian. Voidwalker and Crystallizer are also okay, but mostly in the faster matchups, where you can take advantage of the defensive stat-line to trade into your opponent’s 1-drops. Your 2-drops are also good keeps, as both should be really good to play on the curve – Vulgar Homunculus for the sheer stats and Void Analyst for the effect.
- Keep Doubling Imp with Void Analyst. You can also keep Imps or Saronite Chain Gang with Soul Infusion, but only if Imp/Chain Gang are on the left (or you have some smaller cards on the left that you can play before using Soul Infusion).
- DO NOT KEEP The Soularium. The card is insane, yes, but only in the mid/late game. In the early game it’s pretty bad and you’d rather have something you can actually play.
Great posting friend. Will be back to read more.
Bring back pirate warrior and make every other card wild, give patches rush
I’m having a lot of success running a similar deck, but I have dropped the Soulfire & Doomguards for Demonfire & Felsoul Inquisitor. I know Felsoul Inquisitor is a trash card, but buffed it provides some much needed late-game sustain while you are digging for your finishers.
Do you have any thoughts on this approach?
Tested on the first day of live Boomsday, right now as everyone is experimenting and trying out different decks, this is a relatively cheap and powerful deck, with a strong chance of winning early rank i found out of 10 games i lost 2 due to bad mulligans, otherwise the interactions between all these cards seem very solid and when you’ve dumped your hand that new legendary ‘The Soularium’ does wonders for ending games! honestly the best theorycraft deck out of all the theory crafts for low rank to rank 10, since it’s budget friendly! Would love to see a pro version of zoo for this new meta!
I’d be using void ripper as well. just 1 though.
it is also a demon as well.
Wouldn’t you want to add at least one Void Ripper ? It’s a demon, it can give a boost on crystallizer vulgar homonculus or nethersoul buster, and it’s probably going to be a nice tech in the meta (I don’t see spreading plague going anywhere).
If it was to run Keleseth which I think probably will be stronger, how will the deck list change?
This one is a more serious decklist: AAECAf0GBo+CA5ziAqr5Ap/CAvIFl9MCDPr+AsII8tAC0/gCzgcw9PcC/dACm8sC980C9wTR4QIA
i think that you should drop bloodreaver gul’dan because of the solarium. i think it’s better if you drop gul’dan and nethersoul buster for 2 sea giants
Void Analyst is bad, it’s clearly better to just run Keleseth…
The list is cute with Void Analyst, but we all know that it’s just a bad version of Keleseth, on average. Vulgar Humonculous is the real 2-drop that can compete with Keleseth, and before the rotation I favored that version because it could run Bloodfury Potion, which curved nicely with the Humonculous. So I believe this list will definitely be strong, but a version with Keleseth will be stronger.
is void analyst that good in zoo? you often have a fairly empty hand most of the time and it would feel bad to play after turn 2.
It’s true that later in the game it will rarely give you more than +1/+1, but it can snowball in the early/mid game quite nicely. Just hitting Doubling Imp + one more card makes it really good.
Later in the game, it might be nice to combine Void Analyst with The Soularium. Play Soularium, sac Void Analyst and play buffed Demons if you drew some.
But it’s really hard to say without testing it first. Like I’ve said in the guide itself, I think that Keleseth version might still be better, but in order to find the best version we first need to test each one of them 🙂
Nethersoul Buster is a set sleeper
Yeah, I think that card has some serious potential, I’m only worried about one thing – it’s very weak on the curve. You need to combo it with something, so you can’t play it on T3.
I am playing wild only, and you could drop a turn 2 wrathguard, if it sticks you can trade with it and play the Nethersoul thing on curve with 2/3/4 attack.
