Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryUGPlayers write colors as letters: U for blue, G for green. Blue is U because B was already taken by black.Graveyard/Self-MillGraveyard decks fill their own graveyard on purpose, then play cards from it as if it were a second hand.
