[AUTO]:When this unit is put on (GC), choose a grade 3 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, until end of that battle, this unit gets [Shield]+5000, and when this unit would be retired from (GC), put it into soul instead. [CONT](Soul):When this card would be Soul Blast for the cost of the ability of your "Moon Gate", you may Soul Blast this card while regarding it as two cards.
