Meta Rule:61

Attacks that take place after an opponent concedes are limited to 1 attack to 1 Character. If a Special is played that grants follow-up attacks, the follow-up attacks are forfeited. Cards that requires a teammate's contribution (e.g., DoubleShot cards) can be used. Cards that require a teammates follow-up (teamworks, ally cards) cannot be used. Activator cards can be used.
