Description (934 chars)

Change is coming to the Crucible with the Mass Mutation set for the world’s only Unique Deck Game, KeyForge. Over 200 brand-new cards now enter the cardpool in the game’s fourth set, and the mutative power of the dark æmber has changed many of them, creating strange and unknown versions of once-familiar creatures. As gigantic creatures stretching across two cards lumber their way into battle, and House Sanctum makes its triumphant return, there has never been a more impactful time to leap into the fast-paced duels of KeyForge. Each Mass Mutation Two-Player Starter Set contains two ready-to-play 36-card decks, bringing together three of the diverse Houses of the Crucible—each featuring their own mix of cards and unique from every other Archon Deck in existence. You’ll also find all of the tokens that you need for two players to start playing KeyForge! —description from the publisher
