[ACT](Bind Zone) Generation Break 1 : [Counter Blast (1)] If you have a vanguard with "Chronofang" in its card name, call this card to (RC). Then, you may choose one of your opponent's rear-guards. If you do, your opponent returns that unit to his or her deck, searches his or her deck for up to one card that is a grade less than that unit, calls it to (RC), and shuffles his or her deck. (He or she may stop looking when they do not want to call any card)
