Archangel, Michael

:When this unit is placed on , if your opponent's vanguard is grade 3 or greater, [ a unit with "Marco" in its card name], your opponent chooses up to one card from their hand or rear-guards, discard that card if they chose from their hand, and retire it if they chose from their rear-guards. If your opponent's card was not put into their drop, choose one of your opponent's vanguards, and deal one damage.
