The full set of cards for Murder at Castle Nathria has been revealed a little while ago, and we're nearing the time when they can finally become a part of our collection. Still not sure what to make of Warlock or what kind of decks to play? We've broken down all class archetypes for the upcoming expansion and gathered a variety of theorycraft decks from streamers, pros, and community members to guide you on Day 1.

First off, there is a lot of other relevant content that you might be interested in:

Now, onto what's right around the corner. Before we jump into a variety of potential decks, here is a quick look at the class in the upcoming expansion: 


Castle Nathria Warlock - Quick Imp-ressions

  • Warlock got a ton of support for the Demon sub-category, Imps! We've seen Imps show up in plenty of cards before, but never quite like this.
  • There is also a fair amount of support for Shadow spells. These combine with the existing Abyssal Curse archetype and make Tamsin Roame even stronger.
  • Each package is flexible enough to be slotted into a variety of different decks and even have some crossover with themselves!

Castle Nathria Warlock - Expansion Cards & Archetypes 

For Warlock, two archetypes have asserted themselves as the favorite to play on Day 1: Imps and Shadows spells.


Imp Warlock

Mischievous Imp Card Image Vile Library Card Image Flustered Librarian Card Image 

Warlock is no stranger to flooding the board with Imps with cards like Fiendish Circle, Wicked Shipment, and Imp Gang Boss, but there are rarely massive payoffs for Warlock swarming the board. Enter Impending Catastrophe and Vile Library, possibly two of the strongest payoff cards an archetype has seen. Impending Catastrophe at its worst draws one and draws eight at its best. In most scenarios it will draw between 4-6 given how easy it is to summon Imps, which is absolutely insane for 2 mana. Similarly, Vile Library allows you to take you wide board of imps and translate it into a singular tall threat as well. Imp King Rafaam stands as the center piece of the archetype, providing a minimum of 10/10 in stats (assuming 1/1 Imps are resurrected) with the potential to buff the board as well. This package has a lot going for it and is predicted to dominate the early meta.

While many Imps can be identified by name there are also a handful of cards that count as Imps without being named as such: The Fiend from Dark Alley Pact, Tiny Knight of Evil, Imprisoned Homunculus, Vulgar Homunculus, Street Trickster, Unlicensed Apothecary, Sneaky Devil, Ring Matron, Envoy Rustwix, and Demonizer from Duels.


Shadow Warlock

Lady Darkvein Card Image Shadow Waltz Card Image Shadowborn Card Image

Warlock already has powerful Shadow spell synergy - I'm sure we have all heard of Tamsin Roame by this point. Lady Darkvein is the stand out powerhouse among these cards, since she creates a decent board presence and offers cheap ways of re-casting Shadow spell. Abyssal Wave, Dark Alley Pact, and the new Shadow Waltz are especially potent. Shadowborn offers Control decks with expensive Shadow spells a way to play them earlier, but isn't as flexible as the other cards.


Other Warlock Cards

Tome Tampering Card Image Suffocating Shadows Card Image

Suffocating Shadows is a Shadow spell, but gets lumped with 'other cards' because it isn't strong enough on its own and needs the Discard synergy. There might be some merit to doubling it with Tamsin Roame, but Warlock has far stronger uses for their mana. Tome Tampering is definitely one of the most interesting cards Warlock got from the expansion, but Discard decks are not currently a thing and it remains to be seen if this kind of effect is desirable enough to run.


Castle Nathria Warlock - Top Neutral Cards

Sire Denathrius Card Image Murlocula Card Image

Warlock does not clearly benefit from most of the Neutral cards from Nathria. Sire Denathrius offers Imp Warlock another way to close out games and can be easily Infused with the constant flood of Imps onto the board. Although Warlock does not have a way to specifically draw Denathrius, the enormous card draw from Impending Catastrophe will help ensure he is in hand soon enough to Infuse plenty.

Murlocula fits into the existing Murloc Warlock quite well, although the deck has fallen out of favor. Even so, Murlocula might find a place in an Imp deck. Warlocks can take a lot of damage from their cards and Life Tap, so having a little Lifesteal might go a long way, even more if its buffed by Vile Library. Costing 0 after some Infusing is also especially handy when Imp Warlock can constantly refill its hand with Impending Catastrophe.


Castle Nathria Warlock - Day 1 Decks to Try

Not sure what to play for the class once it's time to enter Castle Nathria? We've gathered a handful of early deck ideas from all across the Hearthstone tavern just to help you out:


Imp Zoolock

NohandsGamer made an Imp Zoolock with slightly less emphasis on the Imps. Thanks to the incredible draw power of Impending Catastrophe, cards like Anetheron and Goldshire Gnoll become much easier to play. Battleground Battlemaster also makes an appearance since it can provide a shocking amount of burst damage when combined with Vile Library.


Full Implock

Trump opted to go far more Imp-focused with his list, including many more cards that summon Imps and cards that support going wide, such as Shady Bartender and Murlocula. The Imp package is fairly flexible and fits very aggressive and midrange playstyles, making it a bit tricky to optimize given how many Imp related cards there are. 


Renathal Curse Control

Old Guardian took pieces of the current Renathal Curse package and slotted in some of the new Shadow tools Warlock is getting. Lady Darkvein represents the potential for two more Abyssal Curses for the opponent, which can be expanded upon even further with Brann Bronzebeard or Zola the Gorgon. Shadow Waltz and Shadowborn offer additional ways to protect the deck from early aggression, either by presenting strong Taunts or by cheating out Abyssal Wave or Twisting Nether three turns earlier.


Wild Mode - Tome Tampering Mecha'tun

MarkMcKz made a Wild Mecha'thun OTK deck featuring Tome Tampering! Wild has many more synergies for Tome Tampering such as Malchezaar's Imp and Hand of Gul'dan, all which help mitigate the immediate value loss from discarding the hand.
