Kobolds and Catacombs Wild Card Spotlight: Carnivorous Cube


It’s that time of year again. With the announcement of Kobolds and Catacombs we have the first spoilers from the new set. I’m here today to talk about my favorite card from the initial spoilers and a card that I think has great potential in the Wild Format:


Carniverous Cube


Carnivorous Cube is a powerful card that enables some incredible synergies and combos, particularly when combined with good Deathrattle effects. At five mana, the Cube itself has a solid base statline at 4/6 which is about on par with other 5 minions. Of course, what makes Carnivorous Cube really shine is its Battlecry: Destroy a Friendly Minion and Deathrattle: Summon 2 copies of it. Carnivorous Cube is a great card for insulating your board against board clears, enabling powerful deathrattles, and doubling your minions. With that said, let’s take a look into some of the powerful synergies that Wild has to offer alongside the Cube.



  • Nerubian Egg and Devilsaur Egg – Carnivorous Cube naturally synergizes with Hearthstone’s “Egg” cards as they provide powerful deathrattle effects for cheap. These cards provide very sticky minions on curve to allow your Carnivorous Cube to land and provide immediate impact with a 4/4 or 5/5 alongside the 4/6. This combo also makes an absolute nightmare for any control to clear
  • Piloted Shredder – Another already solid card and natural card to curve into Carnivorous Cube with.
  • Cairne Bloodhoof, Sylvanas Windrunner, Sneed's Old Shredder, Aya Blackpaw- Combining extremely powerful deathrattle effects alongside the Cube is absolutely insane value.
  • N'Zoth, the Corruptor – Doubling your Deathrattles while also being a Deathrattle Card itself, the Cube can power out powerful N’Zoths early in the game.
  • Faceless Manipulator – When you’re hunger for value can’t be satisfied.
  • Spiritsinger Umbra – It’s not yet clear how things resolve when you target a Spiritsinger Umbra or other minions with the Cube, but I imagine some good things happen. Besides that case, playing Spiritsinger Umbra and trading in the Cube will immediately trigger the Deathrattles of whatever minions were inside the cube, giving potential for some incredible board swings.
  • Baron Rivendare – Baron Rivendare can lead to some incredible doubling in a deck full of Deathrattles and Carnivorous Cube.

Class Cards

While there are plenty of class cards that have powerful deathrattles, I will highlight mostly Hunter cards as it’s the class with the most potential for the Cube. That said, here are some honorable mentions.

Shaman – White Eyes

Rogue – Unearthed Raptor, Sherazin, Corpse Flower, Jade Swarmer, Shadowcaster

Druid – Gains access to a new Aviana and Kun the Forgotten King combo using Deathwing, Faceless Manipulator, and Carnivorous Cube.

Priest – provides three deathrattles for Awaken the Makers.


With plenty of support for a Deathrattle Archetype, Hunter seems like the natural fit for a card like Carnivorous Cube. Let’s take a look at some of the powerful Hunter cards that synergize with Carnivorous cube.

Play Dead – A cheap and efficient deathrattle trigger that can provide immense value and board when combined with the Cube.

Feign Death – The reason to be excited about this Carnivorous Cube in Wild. Already great in Egg style Hunter decks, Feign Death will trigger the Deathrattle of Carnivorous Cube, or can be used to trigger the two Devilsaur Egg left behind, providing huge board presence for a mere two mana.

Terrorscale StalkerPlay Dead on a 3/3 stick  for 3 mana is fantastic when you have powerful death rattles to trigger such as the Cube.

Kindly Grandmother – A cheap, decent Deathrattle option for Hunter.

Corpse Widow – For decks looking to go bigger, Corpse Widow joins Carnivorous Cube as another 5 mana 4/6 with a very powerful effect. Discounting Carnivorous Cube and other Deathrattle minions mitigates some of the innate slowness of many Deathrattle minions.

Princess Huhuran – If you are looking for more enablers, Princess Huhuran is a surprisingly decent option.

Savannah Highmane – The OG king of Deathrattle for Hunters, eating a Savannah Highmane with Carnivorous Cube makes an incredibly resilient board and a very threatening deathrattle from the Cube.

Abominable Bowman – A bit on the slow side, but if you really want to go over the top, Abominable Snowman is one of the largest deathrattles available. Devilsaurs from your Egg, Corpse Widows, and Princess Huhuran are all sizable beasts that can come from Abominable Bowman.

Deck Brew: Deathrattle Hunter

Egg Hunter

Deathrattle Hunter has always been a fringe deck in Wild with skilled pilots capable of hitting legend with the deck. Don’t be fooled by the plethora of 0 power and 1 power minions in this deck; Deathrattle Hunter is capable of putting on pressure early while creating a resilient board.

Using the shell of Control’s Deathrattle Hunter, Carnivorous Cube provides a solid 5 drop and powerful threat against control decks.

The core of the deck are the deathrattle sticky minions Nerubian Egg and Devilsaur Egg. Combined with Play Dead, Feign Death, and Terrorscale Stalker, the deck easily can pop out 4/4s and 5/5s early in the game.

Another way to enable the deathrattle minions are buff effects like the suprisingly good Spawn of N'Zoth, Glaivezooka and Defender of Argus.

Lastly, the deck has a couple of cards that really push the Deathrattle synergies like Spiritsinger Umbra and Baron Rivendare allowing for some crazy value plays.

Carnivorous Cube really pushes the value aspect of the deck to another level, as it acts as both an enabler of the deathrattles and a target for cards like Play Dead and Feign Death.

A more slower variant is worth exploring as well, with cards like N’zoth, Deathstalker Rexxar, or [Corpse Widows] .



Carnivorous Cube does all the things I love about Hearthstone: open up creative deckbuilding opportunities, generate insane value, provides a uniquely powerful effect, and is an absolute blast to play.

Even if the card ends up too slow for the format or not seeing competitive play, its creative design is hopefully an indicator of more cards to come.

Spoiler season is always an exciting time. For Wild in particular, the sheer amount of card combinations with the larger collection that Wild has to offer is mind boggling. I hope you enjoyed and stay tuned for more Wild Card Spotlights!
