Look at Me, I'm the DCI

The DCI, originally short for Duelists’ Convocation International and later short for absolutely nothing, was the name given to the governing body overseeing all Magic organized play. Although this name has since been retired, the card Look at Me, I’m the DCI persists in its honor.

If cards from a player’s main deck are banned, they must replace them with cards from their sideboard to begin the next game of the match. If enough cards are banned such that they can’t meet the deck minimum, they can begin the game with their main deck having fewer cards than is normally required. However, if they end up with fewer than seven cards available, they’ll lose the game as it begins when they are forced to try and draw from their suddenly empty library.

The ban doesn’t affect tokens, including ones that already exist when the ban goes into effect and future ones that may be created.

After you choose a card, all cards with that name are removed from the game in progress, no matter what zone they’re in. If there are any in a player’s sideboard, those are removed as well. Those cards remain out of the game for the rest of that game and for any subsequent game in that match.
