The Crucible is about to be shaken up in Worlds Collide, the third age of KeyForge! In this continuation of the world's first Unique Deck Game, two brand-new Houses enter the fray as 284 new cards are seamlessly integrated into the existing card pool. With new Houses come more new keyword abilities and new styles of play to create an entirely new collection of Archon Decks for you to discover, explore, and master! The KeyForge: Worlds Collide two-player starter set provides you with all the tools you need to either begin or expand your adventures on the Crucible, including two unique Worlds Collide archon decks, a quickstart rulebook, two poster playmats, and all the keys, tokens, and chain trackers you and your opponent need to start playing! —description from the publisher
