An Ability Card is an extremely valuable card to be holding in a deck. In fact, it is so powerful that only a single Ability Card is allowed to be brought to Battle. Unlike the other three Gateway cards, an Ability Card does not have any G-Power Boosts. Instead it has an HSP score and a particular instruction that all Brawlers must obey. An Ability Card is quite forceful and when used properly can have a devastating effect on your opponents.
