Time Leap-[AUTO](VC/RC): [Counter Blast (1)] At the end of the battle that your vanguard attacked, if your drive check did not reveal a trigger unit during this turn, you may pay the cost. If you do, choose one of your other rear-guards, and you may time leap it.

(Bind it, call a grade +1 card from your deck, and shuffle your deck. At the end of the turn, put the called unit on the bottom of your deck, and call the bound card)
