[AUTO](VC/RC):[Counter Blast (1)] When this unit attacks a vanguard, if you have a vanguard with "Magus" in its card name, you may pay the cost. If you do, declare a card name, and reveal the top card of your deck. If the revealed card is the card you declared, put that card into your hand, and this unit gets [Power]+3000 until end of that battle.
