text: 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.
