  • Once a Tactic has been banned, if the Summoner performs that action again, they will gain 1 Token of Blunder.
  • After all 3 Tactics have been banned, they are instantly unbanned and the Grandmaster prepares his Special 1. Tactics cannot be banned again until the Grandmaster has thrown his Special 1.
