[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.
