[AUTO]:[Soul Blast (1)] When this unit is placed on (RC), if you have a grade 3 or greater "Zodiac Time Beast" vanguard, you may pay the cost. If you do, bind the top card of your deck face up, if that card is a "Zodiac Time Beast", choose one of your opponent's rear-guards with grade less than or equal to that card, and your opponent puts that unit on the bottom of his or her deck.
