903.4 The Commander variant uses color identity to determine what cards can be in a deck with a certain commander. The color identity of a card is the color or colors of any mana symbols in that card's mana cost or rules text, plus any colors defined by its characteristic-defining abilities (see rule 604.3) or color indicator (see rule 204).
Le cout de mana et le texte de la carte comprennent les symboles de mana des cinq couleurs, dont son identité colorée est bleu, noir, blanc, rouge et vert.
