Wild Hearthstone has thousands of cards, and a wide variety of possible decks. This incredible deck diversity is sometimes lost when only looking at the few decks common in the highest ranks. Wildest of Wednesdays is a series aiming to highlight a different off meta deck each week with an in depth guide into its strategy and gameplay. The decks are selected for having interesting synergies and using rarely seen cards.

Void Contract. Despite seeing almost no play, it is, in fact, a real card, and this is a deck that can make full use of it and its unique effect, and uses the new Ambassador Faelin to provide a new and powerful win condition after both players' decks have been destroyed. First off, the deck uses Bloodbloom to be able to play Void Contract on turn 4 (or even 3 with the coin). Being able to play it so early means it destroys a larger portion of both decks. It uses Altar of Fire and Gnomeferatu to remove more of your and your opponent's cards. The point of destroying your opponent's deck is for disruption - you get rid of any combos and possible win cons they might have.

For your own deck, you actually benefit from Void Contract destroying it - having your deck size get low means you get to activate cards like Barrens Scavenger, Blood Shard Bristleback, Zephrys the Great, and Reno Jackson to help with survival. Finally, you have multiple powerful win conditions, even one of which will often give you the win in the lategame after both decks have been destroyed or close to it: Chef Nomi, Ambassador Faelin, Archivist Elysiana, and Neeru Fireblade.

Overall, Void Contract Warlock uses Void Contract to great effect both to disrupt your opponent's plans and to enable powerful finishers like Chef Nomi. Void Contract is very, very rarely seen, but with Ambassador Faelin, it can finally have a deck that actually has a unique, coherent and enjoyable gameplan. If you like disruption, Ambassador Faelin, or want to seriously surprise your opponents, give Void Contract Warlock a try!

Huge Thanks and Credit for Void Contract Warlock deck development to Java - it wouldn't have been possible without him!

Now, let's get into a guide on playing the deck. It's going to go through major overarching strategies to keep in mind, how to mulligan, gameplay tips on key synergies, and card choices.


First you will destroy much of both decks with deck burn cards, while using removals and heals to stall. Then you will have some powerful stabilization tools come online that only work if your deck size is low, and finally you finish off the opponent who will have an empty or close to empty deck with one of your powerful win condition cards that work when your deck is gone or almost gone (you have 5 possible finishers, and the chance that all are burned is very low).

Deck Burn - You use Void Contract along with Bloodbloom to discount it as your main source of deck burn - this can burn over 10 cards from each deck in one go. You can also use Altar of Fire and Gnomeferatu for more burn afterwards.

Survival - You have powerful Warlock tools including Defile, Dark Skies, and Dreadlich Tamsin to remove enemy minions and keep the board clear. After enough deck burn and card draw, you will have Reno Jackson active for a full heal, Zephrys the Great for clears, Barrens Scavenger as a cheap Taunt, and Blood Shard Bristleback for healing and removal. This ties into your deck burn strategy - the faster you can burn your own deck, the faster you get these powerful survival options online.

Finisher - At some point - starting as early as turn 5 depending on your draws - both decks will be empty or close to it. The deck has 3 main finishers and a backup option to close out games that reach this state and go into fatigue. Neeru Fireblade opens a portal for a full board of 3/2 imps each turn, while Archivist Elysiana and Ambassador Faelin refill your deck, staving off 10 turns of fatigue. Finally, Zephrys the Great can get Lord Jaraxxus to provide consistent board pressure. Chef Nomi can win you the game with board pressure as well.

The deck can struggle against aggro because deck burn is inherently low tempo, although it does have removals and heals to be able to comeback and win against aggressive decks sometimes. Void Contract Warlock is really good against slower decks including midrange, control, and especially combo where you can burn either value or combo win conditions and then finish off the game with one of your own.

Here are two pictures which show what the deck can do: A game with both decks destroyed and Neeru Fireblade up; and using Bloodbloom Void Contract into double Altar of Fire and Gnomeferatu early to destroy the opponent’s deck by the end of turn 5.


I have never seen any other deck (including Tickatus decks) destroy so many cards so early - even with their best highrolls such as from The Dark Portal - and having the possibility for this sort of thing makes Void Contract Warlock unique and extra enjoyable to play.


  • Try to get Bloodbloom and Void Contract (one copy of each). If you have one but not the other, mulligan everything else away to get the other. This combo is crucial to this deck, so you should mulligan to get it as the first priority.
  • If you already have a Bloodbloom and a Void Contract, you can keep a second copy if you really want to destroy both decks quickly, but the more optimal mulligan choice is to only keep one of each.
  • If you have one of each, you can keep any win condition card you like in hand.
  • You can also keep anti-aggro spells such as Defile and Dark Skies in this scenario, or more burn like Altar of Fire and Gnomeferatus if you want to go for maximum early deck destruction. It really depends on if you think you’re against aggro, combo, or control, and if you want to risk losing to aggro to have a chance at the very epic turn 5 both decks have been destroyed scenario.


The key to playing this deck well is being able to fit in your low tempo burn turns at the right moments while using your removal, Taunts, and heals on other turns to be able to survive to your endgame.

Below are gameplay tips regarding many of the synergies in this deck and how to use them effectively.

Void Contracts and other Deck Destruction

First of all, you should try to combo Void Contract with Bloodbloom to be able to play it for 4 mana. Playing it for 8 is alright against slow control or combo decks, but even then it's usually better to combo it with Bloodbloom so you can use the 4 mana you save on other things.

Void Contract rounds up if there is an odd number of cards in a deck. This can be relevant to keep in mind, as if you have 21 cards in the deck before Void Contract you'll have 10 after and your Blood Shard Bristlebacks and Barrens Scavengers will become active.

When should you play Void Contract? In general, as early as you can as it has more of an impact since it destroys half the deck and the deck size keeps decreasing. You have 5 cards that provide you with a win condition after both decks have been totally destroyed, and you usually only need one to win. Therefore, even if you have not drawn any of those (Neeru Fireblade, Chef Nomi, Archivist Elysiana, Ambassador Faelin, and Zephrys the Great), it's still safe to play Void Contract as there's only a 1/16th chance that all 4 of these will be in the top half of your deck.

If you are low on health, don't play Void Contract Bloodbloom as soon as possible - instead, you can time it so that you play it when you have 21 cards in your deck and so are left with 10 cards after doing so. This way, you can play Blood Shard Bristlebacks that same turn to deal damage and restore health and Barrens Scavengers for 1 mana to set up a Taunt wall.

Since Void Contract destroys half of each deck but Altar of Fire and Gnomeferatu always remove a fixed number of cards, it's better to save them for after you have played Void Contract to burn the maximum number of cards in total. However, if you need tempo and have no other play, you can play a Gnomeferatu just for its 2/3 body. Also, if you see you are close to a 10 card deck but haven't been able to get the Void Contract Bloodbloom combo off yet, you may want to use Altar of Fires to destroy your own deck despite making a future Void Contract less effective to be able to activate your Blood Shard Bristlebacks and Barrens Scavengers faster.

After you have played Void Contract, if you don't have a single win condition in hand, it's risky to start using your Altars of Fire. You should save them for a bit while you draw into one of your finishers. After you have a win condition in hand, you can safely start going all-in on deck destruction with Altar of Fires. You usually don't need more than one win condition, so it's better to go to the endgame scenario faster than wait to get more than one in your hand.

You should tap aggressively in the early turns if you are not under a lot of pressure - using your hero power to get the Void Contract Bloodbloom combo faster is generally better than playing a Gnomeferatu or Armor Vendor on an early turn. Even if you have card draw like Kobold Librarian on turn 2, it's better to tap and then use a tap and the Kobold Librarian on turn 3 for maximum draw.

Endgame Tips

If you have both Archivist Elysiana and Ambassador Faelin in hand, always choose Ambassador Faelin as the card to play. His colossals are stronger than cards you may discover.

After you play Ambassador Faelin or Archivist Elysiana, Blood Shard Bristlebacks and Barrens Scavengers will still have their bonus effects active as the deck size will become exactly 10. However, Zephrys the Great, Reno Jackson, and Neeru Fireblade will become inactive. Therefore, in most cases (unless you are really desperate to prevent fatigue damage, or want to get started drawing colossal faster) you should play these 3 cards before Ambassador Faelin or Elysiana refills the deck.

You can play Ambassador Faelin before your deck is empty, just keep in mind this may negatively affect cards like Bloodshard Bristleback.

Your ideal endgame scenario is both decks destroyed and you having controlled the board and your health total with your survival cards, with one or more win win condition cards in hand. Then, you play them to give you the edge and win by a large amount of board pressure (with Neeru, Chef Nomi, or Lord Jaraxxus from Zephrys) or fatigue (with Elysiana or Ambassador Faelin). You really do need five finisher cards in this deck for consistency given the amount of burning you are going to do, but don't worry about burning any one of these win cons - some are stronger than others but in general, any one of these finishers can be enough to win even if 4 of the 5 got burned.

If you see that you have Neeru Fireblade in hand as well as either Archivist Elysiana or Ambassador Faelin, don't be afraid to play Neeru as a 5/5 body for tempo on turn 5 if you're facing board pressure and need the tempo, having no better plays or clears available. Elysiana or Ambassador Faelin are more than enough to win.

Zephrys the Great can combine with a board of 3/2 imps generated by Neeru Fireblade to give Bloodlust for lethal. You can trade one imp in to be able to play Zephrys and use Bloodlust on 6 imps for a total of 36 damage.

Brann Synergies

The main cards you want to use with Brann Bronzebeard are Gnomeferatus for more deck burn and Blood Shard Bristlebacks for more damage and healing.

Using him with Zephrys the Great to get more clears can be good as well, and you can use him with Armor Vendors and Kobold Librarians too. This happens rarely, but if Brann survives to turn 6 he can combo with Dreadlich Tamsin - this deals 6 damage to all minions but be careful to avoid milling yourself too much as it will also draw 6 cards.

You can use him with Ambassador Faelin as well.

Don't use Brann with Neeru Fireblade - two portals are worse than one as there is less space for imps. Try to trade Brann away if he is on the board when you're about to play Neeru. You should also be careful about playing Archivist Elysiana when Brann is on the board, as he will make her 5 discovers trigger twice and only the second 5 will actually end up in your deck in the end. This means you discover 10 times, but only 5 are actually relevant. Discovering 10 times takes a lot of time, so you should choose quickly for the first 5 - don't spend time thinking to make the optimal choice - and then actually focus on making the right discover decisions for the next 5.

Card Choices

This section is going to go through the main packages of cards in the deck. Each package has cards that help the deck with a specific goal. When playing the deck, it's useful to know what purposes each card serves and what other cards in the deck have synergy with it or help achieve the same purpose. This section might also be useful if you're interested in the reasoning for why each card was included in the deck.

Something to note is that Brann Bronzebeard is not part of any card package but is generally good to get extra value from Battlecries.

Void Contract Package

Bloodbloom Card Image Void Contract Card Image

These cards combine for you to be able to play Void Contract for only 4 mana, albeit at the cost of 8 health. This is key to allow Void Contract to be played early and have the most impact.

Supplementary Deck Destruction

Altar of Fire Card Image Gnomeferatu Card Image

These cards supplement the overall deck destruction gameplan of Void Contract.

Removals and Anti-Aggro

 Armor Vendor Card Image Defile Card Image

Dark Skies Card Image Dreadlich Tamsin Card Image

These cards help you gain armor and clear enemy boards that develop after your low tempo deck destruction turns, and are all active before your deck size gets low.

After-Burn Stabilization

Zephrys the Great Card Image Blood Shard Bristleback Card Image

Barrens Scavenger Card Image Reno Jackson Card Image

These cards will be active once your deck size is low, 10 cards or less for Blood Shard Bristleback and Barrens Scavenger and around that area for Zephrys the Great and Reno Jackson (sometimes it takes a bit more deck destruction or drawing to get them active). These cards heal, provide Taunt, destroy enemy minions, and generally make it possible to stabilize the board and your health total after you spent 8 health and 4 mana on a Bloodbloom - Void Contract play and lost tempo.

Card Draw and Value Generation

Raise Dead Card Image Kobold Librarian Card Image  Dreadlich Tamsin Card Image

Drawing cards helps you get your deck emptied faster as well as get to your Void Contract - Bloodbloom combo more consistently. Raise Dead generates value and can get key minions back.

Win Conditions

Zephrys the Great Card Image Neeru Fireblade Card Image

Archivist Elysiana Card Image Chef Nomi Card Image Ambassador Faelin Card Image

Neeru Fireblade, Archivist Elysiana, Chef Nomi, and Ambassador Faelin are your main win conditions, which you want to activate when your deck is completely or almost completely empty. After both decks have been destroyed by Void Contract and other deck destruction, any of these can provide the final value push to win the game. You can also use Zephrys the Great to get you Lord Jaraxxus as a backup win condition if all three of these got burned.

Void Contract Warlock is a deck that uses Void Contract to its full potential while having a very neat endgame with Ambassador Faelin, Neeru, and other powerful finishers. This is a supremely fun and unique deck for both disruption effects and value. If you have a question or comment, or are wondering about a card substitution, post below.

    Fun deck.  I went 0-3 and was getting the hang of it by match 3 versus a clown druid.  I burned the druids deck and had Kazakusan and Elysiana but he was able to corrupt his clowns and put them out.  I had no counter for all the clowns and had to concede.  I know I had a few misplays but had a lot of fun trying out the deck.  I don't often play Warlock but really enjoyed it.  Thanks for the list.

      Thanks for commenting! Nice to know someone is trying it. I think you’ll get some wins eventually, it’s definitely not as straightforward as most decks but also something like a full board of clowns is tough to deal with. If you face a combo deck you should crush them, and some of the highrolls you can do can lead to very fun and memorable wins even if it’s not that competitive overall.
