[AUTO]:[Soul Blast (1)] When this unit is placed on (RC), if your vanguard is Legion, you may pay the cost. If you do, choose one of your rear-guards not named "Transformation Stealth Rogue, Kuzunoha", search your deck for up to one card with the same name as that unit, call it to (RC), shuffle your deck, and at the end of that turn, put the unit called with this effect on the bottom of your deck.
