903.13f

Commander Draft deck construction follows the same rules as Commander deck construction (see rule 903.5) with three exceptions: (1) A player’s deck must contain at least 60 cards. There is no maximum deck size. (2) A player’s deck may include any number of cards from that player’s card pool with the same name. (3) If the draft contained draft boosters from Commander Masters, any card which can be a player’s commander by itself and whose color identity includes one or fewer colors is considered to have the partner ability for the purposes of deckbuilding. (See rule 702.124, “Partner.”)
