Abstract: A card-based metagame includes a first deck of cards used to play a game according to a set of rules. The card-based metagame also includes a second deck of cards used to change the play of the game. The first deck may be the standard playing card deck or the 52-card deck of French playing cards. The cards of the second deck may be different than the cards of the first deck. In some implementations, the first and/or second decks of cards are physical cards. In other implementations, the first and/or second decks of cards are digital representations of cards provided by a computing device.
