  • *Cards with the same card number but with different illustrations are also considered the same cards.

Selection and Announcement, and Enforcement.

  • ・We will closely monitor the win-rates, tournament results, and usage of certain decks to consider enforcing restrictions if certain decks deviate from our game’s objective.
  • ・Please note that depending on the environment of the game, the status of [Restricted Cards] may change.
  • ・We will continue to announce considerations for these restrictions through official broadcasts after major events and tournaments, Producer’s Letters, and the official Twitter. When this page is updated, there will be a post on the official Twitter as well.
  • ・We plan to review the restricted card list once every 6 months and will only lift restrictions on cards if we do not observe a significant bias in the outcome of the events.
