Casual

Casual refers to playing Magic: The Gathering without an attempt being made to have tournament-worthy decks or be really competitive. Casual players, making up a significant majority of the customer base for the game, are generally more concerned about having fun than winning. Casual games are often played with theme decks that possess a unifying idea, image, or motif, repeated or developed throughout. Listed here are a number of casual formats that range from somewhat goofy to completely crazy. With a few exceptions, there are no "official rules" for these formats.

As with sanctioned formats, most casual variants can be categorised into Constructed, Limited and Multiplayer formats. Some formatis only appear in Magic Online.
