In the game scene of WIXOSS PARTY/CEREMONY and other official/authorized events, cards that severely limit the possibilities of various other deck choices and card selections, or cards that greatly affect the progress of the game by consuming an extremely limited amount of time for only one side are added to the "Mayu's Room".
The specific rules for these cards in the "Mayu's Room" are determined based on their characteristics, and the rules may be changed or they may be removed from the "Mayu's Room" due to changes in the tournament environment.
