Mysticana is a Foundation Deck: an 18-card deck that includes multiple core games using just the base cards with even more games added through small expansions. The deck features cards numbered 1-6 across 3 suits (elements) which have a “rock-paper-scissors” hierarchy. While each game might make use of the deck’s design in different ways, the flexible foundation enables new games to fit in seamlessly alongside previous entries.

The base deck includes rules for three core games: Nine Perils, Sorcerers' Showdown, and The Path Ahead. Two additional expansion games, Cave of Djinns and Arcane Artifacts, are available in this campaign. More expansions will come out over the course of a year.
