Deathwing has arrived.
CATACLYSM is now live with 135 brand-new collectible cards, fresh mechanics, and a whole lot of fire. The battlefield trembles with the return of Colossal minions, the debut of the devastating Herald and Shatter keywords, and new dragonflight cards.
And for the first time in Hearthstone history… you don’t just face Deathwing. You become him.
What’s Included: Deathwing, Worldbreaker Hero Card
Descend upon your enemies as the Destroyer himself with the Deathwing, Worldbreaker Hero Card.

When you transform into Deathwing, you’ll unleash your own personal Cataclysm, choosing from four apocalyptic abilities. Topple the mightiest enemy minion. Scorch the board in dragonfire. Enthrall mighty creatures to your side. Fill your deck with your powerful progeny.
But why stop at one Cataclysm? The more you’ve used the new Herald keyword, the more world-ending powers you’ll command when Deathwing arrives!
The end of the world has never felt so good.

What’s Included: The Return of Colossals
Deathwing is not invading Azeroth alone. Marching beside him are six fearsome Lieutenants, each a Colossal minion so massive they break the limits of the board itself. Colossals expand into multiple cards, their enormous appendages (towering arms, extra heads, giant wings, etc.) spilling across the battlefield. Each appendage has its own ability that complements the core Colossal.
All classes receive a new Legendary Colossal minion
The six classes aligned with Deathwing (Demon Hunter, Death Knight, Rogue, Shaman, Warrior, and Warlock) also wield the Herald keyword, which improves their Colossal minion




What’s Included: New Keyword – Herald
The Herald keyword sounds the drums of doom.
Whenever you play a card with Herald, you’ll summon a Soldier from your Colossal’s army, each bearing the same ability as your class Colossal’s appendages. While Colossals arrive later in the game, Herald gives your opponent a taste of the destruction to come.
But Herald doesn’t just preview, it empowers. Here’s how:
- Use Herald twice to double the power of your Colossal and its appendages
- Use it two more times to double it again and reach maximum devastation
- Deathwing works in a similar way. Herald twice to unleash two Cataclysms. Herald four times to use all four of Deathwing’s world‑breaking abilities!



What’s Included: Dragonflight Defenders
Not all dragons kneel to the Destroyer.
The other five classes (Mage, Hunter, Paladin, Priest, and Druid) stand as champions of the dragonflights, still fighting to save Azeroth. Each class commands a Legendary Dragon Aspect, ready to defy Deathwing and push back the end of the world.


What’s Included: New Keyword – Shatter
Azeroth lies in ruins, but heroes can still piece it back together.
Cards with the Shatter keyword break in two when added to your hand, splitting apart and moving to opposite ends of your hand. You may play each fragment on its own, but if you play the cards between them and bring the pieces together, they recombine into a single card with two powerful effects.


Triumphs and Last Stands
The heroes of Azeroth are putting everything on the line to stop Deathwing and his invasion force. Some will prevail. Others will fall. Pay close attention to the artwork throughout CATACLYSM to see their fate unfold, whether it ends in triumphant victory or a defiant last stand.
