Bounce (バウンス Baunsu) is an unofficial term for ability with effect that return one or more Z/X in Square to the hand or deck. It is considered as one of the main ability of Blue cards.

Bouncing is considered as a kind of temporary "removal", since the returned cards can be played again. It is also used to disrupt the opponent's tempo and strategy, as well as a means of gaining advantage since the empty Square can be occupied with your own Z/X.
