Blizzard's Hearthstone expansion CATACLYSM is live with 135 new cards, a Deathwing, Worldbreaker hero, six Colossals, and new mechanics Herald and Shatter; Dragonflight Defenders join several classes, Dream City Trial Cards are free during the event, and a Tavern Pass offers extra rewards ahead of patch 35.0 notes.
Hearthstone enters its 12th year with Cataclysm, an expansion releasing March 17 in the Year of the Scarab that reimagines WoW’s Cataclysm with Deathwing as the antagonist. In-universe, Murozond pulls Deathwing into Hearthstone, and Chromie with the Dragonflights recruit heroes from across time to defeat him. The update brings Colossal minions (each class gets one, plus six Deathwing lieutenants) and two new keywords, Herald (stacking with Deathwing-related cards) and Shatter (Dragonflights split for flexibility). Players will also see class-based Triumph and Last Stand spells, milestones for community rewards (including a Cataclysm signature), and March 10 trial cards for Emerald Dream and Lost City of Un'Goro during Cataclysm. A Core Set rotation accompanies the Year of the Scarab, with Core Set remaining free and aims for a stronger, more fluid meta. Visual updates, a new game board, and a Legend card back reward for 2026 top players are planned, with first-time Legend earners receiving both the new and classic backs.
Blizzard says Hearthstone’s appeal comes from digital-only mechanics, and there’s no announcement or development work toward making physical Hearthstone cards; the team plans to keep Hearthstone as the premier digital card game while the trading-card boom continues, with upcoming digital updates such as a Cataclysm expansion tie-in.
Blizzard says there will be no Hearthstone 2, clarifying that a BlizzCon 2026 reveal will be bigger than usual but not a new game. The Hearthstone expansion Cataclysm is coming March 17, bringing new mechanics and Colossals, plus a temporary unlock of cards from recent sets. The company also reiterates Hearthstone won’t be on consoles or handhelds yet, though platform considerations—potentially influenced by Microsoft—are being explored for the future.
