KeyForge: Mass Mutation – Archon Deck
A ready-to-play, single-player deck contains 36 unique cards drawn from three of the game's factions. Players use their deck to battle an opponent by playing creatures, artifacts and actions tied to the deck’s Houses, collecting æmber to forge keys while disrupting the opponent’s plans. The set adds over 200 new cards to the card pool, including mutated variants and large double-card creatures that alter interactions and board presence. Each deck is mechanically unique, with a fixed composition and exclusive combinations of cards and a unique identifier, so games focus on deck-driven strategy and tactical sequencing.
