[AUTO](RC):When placed, if your vanguard is "Shura Stealth Dragon, Kujikiricongo", this unit gets [Power]+3000 until end of turn. Then, COST [Counter Blast (2)], return all of your opponent's rear-guards in the same column as this unit to the hand, your opponent chooses the same number of cards from his or her hand as the number of returned cards, and discards them.
