Wielder of Time-Splitting Sword, Bercouli (SAO/S100-E048) is a level 2 character from the Animation Sword Art Online 10th Anniversary set with the traits Anniversary, Fluctlight, and Integrity Knight. When placed from hand to stage, it may target an opponent's level 1 or higher character to trigger an exchange with a character in their waiting room up to one level lower than the chosen target. The effect can disrupt opponent board development by forcing them to swap in a weaker waiting-room character, potentially enabling tempo or setup plays for the controller.
