[AUTO](RC):When the attack this unit boosted hits a vanguard, choose a grade 3 card with "Rezael" in its card name from your ride deck, and you may reveal it. If you revealed a card, or you have a grade 3 or greater vanguard with "Rezael" in its card name, look at the top seven cards of your deck, choose up to one card with "Mythisch" in its card name from among them, reveal it and put it into hand, and shuffle the deck. If you put a card, put this unit into soul.
