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 glossaryURPlayers write colors as letters: U for blue, R for red. Blue is U because B was already taken by black.SpellslingerSpellslinger decks cast lots of instants and sorceries, one-time spells, and play creatures that reward every spell you cast.
