Table of Contents

This version of Cubelock was popularised by pro player Dog at the start of the Kobolds and Catacombs meta. He took the build to Rank 1 Legend. The inclusion of Rin, the First Disciple makes the deck strong in the mirror match.

3. Strategy

The main strategy of the deck is to get a Doomguard into play without casting it, and then use Carnivorous Cube on the Doomguard to get a lot of value from it. For this to happen, your aim is to survive any early onslaught from your opponent. The deck has numerous intricate interactions, and playing it well will require a lot of practice. However, unlike many other difficult decks, this deck is not particularly punishing, and is suitable for most levels of play.

3.1. Mulligan

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, and failing that, you will want Possessed Lackey. This is because you will need at least one way to get early Demons into play without having to cast them.

Beyond the Demon synergy, you will be trying to defend early on. This makes Plated Beetle, Mistress of Mixtures, @Mortal Coil, and Lesser Amethyst Spellstone all reasonable cards to keep. If you know you are up a deck of small minions that will go wide early on, you will be looking for Hellfire.

3.2. Early Game

At the start of the game, you will want 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. Your main plan to do this will be to use Kobold Librarian, Mistress of Mixtures, and Plated Beetle to occupy the board. You will often clear the board early on with Hellfire.

3.3. Mid Game

From Turn 5 onwards, you will be trying to use Skull of the Man'ari and Possessed Lackey to get a free Demon into play. If the Demon is Voidlord, you will take very little damage from minions for several turns. If it is Doomguard, then you will be able to use Carnivorous Cube on it 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 5/5 minion, such as a Corridor Creeper, and then play your Cube.

3.4. Late Game

The late-game 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.

If you are against another Control deck, it is usually strong to get Rin, the First Disciple rolling as soon as possible. If you can put pressure on your opponent to make plays in case they lose their deck, you can often make them use their cards inefficiently.

4. Individual Card Strategies

This section is more important than usual, as cards can serve very different purposes depending on the situation. Mastery of this deck involves understanding the role of each card in the deck.

4.1. Dark Pact

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.

4.2. Kobold Librarian

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.

4.3. Possessed Lackey

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.

4.4. Spiritsinger Umbra

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, such as Mistress of Mixtures, although such interactions are used much more rarely than the Cube one.
