The KeyForge cardpool grows and expands once more with Mass Mutation, giving you access to billions upon billions more completely unique decks—decks with their own strategies and tactics that only you can truly master. Drawing from a cardpool of 422 cards, Mass Mutation brings over 250 brand-new cards to your decks, and with the introduction of dark æmber, mutation runs rampant. You’ll find strange new versions of familiar characters, massive creatures that stretch across more than one card, and the triumphant return of House Sanctum.
As with previous sets of KeyForge, there are plenty of ways for you to enter the game. If you’re already playing, you can easily pick up an assortment of Mass Mutation Archon Decks, each offering a ready-to-play unique deck. Or, if you’re getting into the game for the first time, the Mass Mutation Deluxe Deck contains one deck and tokens for one player, while the Two-Player Starter Set contains two decks, paper playmats, and tokens for you and your opponent. Whether you’ve been playing KeyForge since the first day, or it’s just now catching your eye, Mass Mutation is the perfect time to get started.
