Wild Cubelock (Cube Warlock) Deck List Guide - Rise of Shadows April 2019
This guide to Cubelock includes strategy advice, as well as information on variants of the deck.
Cubelock originated during the Kobolds and Catacombs meta as a combo deck which used Carnivorous Cube. Possessed Lackey, and Spiritsinger Umbra to create multiple Doomguards and win over the course of one or two turns by inflicting massive damage. The deck used Bloodreaver Gul'dan to re-use the Doomguards if the game went that long.
Although this basic premise for the deck still remains to some extent, the deck has developed so that it can do so much more. It can still win in the original manner, but can also win by setting up a wall of Voidlords to shut the opponent out of the game. With this versatility, Cubelock has become one of the best — and most feared — decks in Hearthstone.
Despite being an extremely difficult deck to play optimally, the power level of the deck is so strong that it can be used by anybody with some Hearthstone experience to get good results.

Aim of Wild Cubelock (Cube Warlock)
The aim of the deck is to gain a big advantage on board through the use of Possessed Lackey, Carnivorous Cube, and Skull of the Man'ari to get strong minions into play faster than would normally be possible.
The deck uses its versatility to either kill the opponent rapidly, or to set up a huge wall of defenders, depending on the situation. As it has multiple ways to do this, it is remarkably consistent and this makes it one of the most powerful decks in the game.
Warlock has an extremely powerful Hero Power, Life Tap. This means that the deck has very good consistency when the Life Tap is efficiently used.
The fact that this is a combo-orientated deck, rather than a control deck, really stands out in the mulligan phase of the game. You are looking for Skull of the Man'ari in your opening hand. This is because you will need at least one way to get early Demons into play without having to cast them. Although Possessed Lackey is also good, you will only keep this if the rest of your hand is strong, as it is too slow to control the early board.
Beyond the Demon synergy, you will be trying to defend early on. This makes Defile, Hellfire, Kobold Librarian, and Doomsayer all reasonable cards to keep. If you know you are up against a deck that produces one large minion, you can keep Lesser Amethyst Spellstones.
Against Control decks, the mulligan strategy changes significantly. Bloodreaver Gul'dan becomes an extremely strong card, and in the mirror you will be looking for this and Mountain Giant almost exclusively. You can still keep Kobold Librarian as there is no downside to doing so.
Wild Cubelock (Cube Warlock) Early Turns
At the start of the game, you will be looking to slow down your opponent as much as possible. Unless you have a spectacular hand, you will also be looking to maximize your Life Tap Hero Power to draw as many cards as possible. You should not be afraid to use this ability, as although you take damage, you lower the cost of your Mountain Giants and get closer to being able to get an early Voidlord which will more than compensate for the lost Health. Against extremely aggressive decks, you will have to consider how much damage you can take from the Life Tap. It is important to realise, however, that the more cards you draw the closer you get to the healing cards and Taunts that could help you to stabilise.
If your opponent is playing around Defile while making a wide board, you can keep back your Kobold Librarian, and play it on the same turn as you play Defile so as to make sure that the Defile has a 1-Health minion to kill.
Wild Cubelock (Cube Warlock) Later Turns
From Turn 5 onwards, you will be trying to use Skull of the Man'ari and Possessed Lackey to get a Demon into play from either your hand or your deck. If the Demon is Voidlord, you will take very little damage from opposing minions for several turns. If it is Doomguard, then you will be looking to use Carnivorous Cube on it, and then Dark Pact the Cube, to generate more Doomguards on the following turn. It is important that you get any value out of Doomguard that you can before removing it with the Cube. A very common play is to trade into an opposing minion, and then play your Cube. Bear in mind that due to the popularity of Cubelock, as well as buff cards in other decks, Silence effects are very common. It is usually incorrect to use your Cube if there is a strong chance that your opponent can Silence it before you can kill it off yourself.
You will also need to be aware when the Silence effect is inevitable. In some games you will realise that your opponent is going to silence something at some point, and at that stage will need to make a decision as to what you do not mind being hit. If your opponent is playing an aggressive deck and you are expecting to spend nine Mana on a Voidlord, you might try to get them to Silence something else before that becomes a problem. Against very aggressive decks, you can also sometimes use Dark Pact on your own Voidlord so that Silence or bounce does not allow your opponent to attack for lethal damage.
Wild Cubelock (Cube Warlock) Endgame
The endgame varies a lot from game to game, but it will usually involve playing Bloodreaver Gul'dan to bring back either several Doomguards in one turn, or a huge amount of Taunts from Voidlord and the Voidwalkers that the Voidlord produced. Against minion-based decks, this usually signals a victory.
Against slower decks, you will be able to gain incremental advantage using your Hero Power. Over time, this will give enough value to allow you to find a way to finish the game. Sometimes that will involve a slow process of gradual pings, other times it will be a catalyst for you to be able to get a large amount of Doomguard damage over one or two turns.
Individual Card Strategies
The timing of your Dark Pact play can be very important. The primary purpose is to be able to remove your Carnivorous Cube or Possessed Lackey on the turn which you play it. This helps you to avoid any Silence effects that your opponent might have.
In other situations, you should usually try to hold onto the Dark Pact for as long as possible to maximize the healing gained from it, and to withhold the information from your opponent as to how much damage they need to do to you. This can cause them to overextend, or to waste their burn.
Kobold Librarian effectively does the same thing as Life Tap, but for 1 less Mana, and also puts a minion into play. The part that can be overlooked with the Librarian is that it can often be used in the late game to improve the damage output of any Lesser Amethyst Spellstones that you have managed to hang onto. Given that the Lifesteal moves up by 2 damage each time the Spellstone is upgraded, this means that the Librarian does not cost any Health to play.
Possessed Lackey can often be played onto the board with the anticipation of getting a Demon into play on the following turn. However, this can sometimes play into Silence effects. Unlike Carnivorous Cube, you will often be able to kill your Lackey with Defile should Dark Pact be unavailable.
Spiritsinger Umbra can be played on the same turn as Carnivorous Cube for a total of 9 Mana. When you do this, the Cube will remove the targeted minion from play, and then produce two more immediately. This means that a single Doomguard can do 15 points of damage! It is worth remembering that the Spiritsinger can be used on other cards, although such interactions are used much more rarely than the Cube one.
When you play the Spiritsinger, your opponent will be terrified of it. This means you can sometimes play it without anything to activate to buy yourself some time. You can also sometimes play it on Turn 4 if you are reasonably sure that your opponent cannot deal with it. If you have The Coin, this can lead into a Turn 5 Possessed Lackey and instantly trigger the Deathrattle.
Key Cards and Swaps
Bloodreaver Gul'dan is essential to the deck. Without this card, you will not have a good feel for how the deck plays, and in many matchups you will not have a win condition. It is not recommended that you try the deck without this card.
Skull of the Man'ari and Lord Godfrey are both extremely important to the deck, but are not absolutely essential. Although it is not recommended that you play without them, especially the Skull, you can probably get a feel for how the deck works if you want to try it out in casual before crafting. The Skull is a better card to craft than Godfrey if you only intend to craft one of the cards.
Spiritsinger Umbra and Prince Taldaram are very strong cards, but are not essential to the deck. You can replace Prince Taldaram in addition to the other card mentioned with multiple 3-Cost cards like Tar Creeper and Voodoo Doll.
Quick Tips and Tricks
- Remember that Kobold Librarian and Possessed Lackey can be used to fill in gaps for Defile. This means that if you are expecting your opponent to play around Defile, you can keep these cards back to help you to clear the board.
- Be aware that Voidlord, Carnivorous Cube, and Possessed Lackey are susceptible to Silence effects. Try to get the least important one silenced where possible.
- If you know your opponent is playing a lot of weapon removal, think carefully before playing Skull of the Man'ari if you have other options, or if missing your turn could be fatal.
- Keep an eye on the casting cost of your Mountain Giants. If you tap correctly, you should be able to play them for 4 Mana on Turn four.
