After the shuffle, the deck must be offered to the player’s opponent to be cut once. Cutting the deck consists of creating two separate stacks of cards by removing a portion of the top of the deck, and then placing it under the remaining portion. Players should take care to not reveal any of their opponent’s cards while cutting. Cutting into more than two stacks is considered a shuffle.
Instead of cutting, the opponent may choose to shuffle the deck. This shuffle should be brief, and when it concludes, the deck’s owner is allowed to cut the deck once as described above. Players should take care when shuffling an opponent’s deck, as the cards in that deck are not the shuffling player’s property. At this point, the deck should be sufficiently randomized to both players’ satisfaction.
If either player still does not feel that either deck is sufficiently randomized, or if a player prefers not to offer his or her deck to an opponent for randomization, a judge must be called over to shuffle the deck(s) in question. No player is allowed to shuffle or cut after the judge’s shuffle.
