Commander also known as EDH is a casual eternal Constructed multiplayer format.
Decks consist of 100 cards and no sideboard, one of which is a legendary creature chosen as a commander.
Except for basic lands, all cards are allowed in only 1 copy. No card is allowed if its color identity contains colors outside color identity of the chosen commander.
