[AUTO]:[Counter-Blast 1] When this unit is placed on (VC) or (RC), if you have a vanguard, you may pay the cost. If you do, choose one of your rear-guards not named "Stealth Fiend, Oboro Cart", search your deck for up to one card with the same card 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.
