Cursed Souls Squirming in Agony

Play this with [COST][Soul-Blast 2]! Look at four cards from the top of your deck, choose up to one unit card from among them, call it to (RC), and discard the rest. If during Alchemagic, call up to two cards instead of one to (RC), and all of this order's called units get [Power] +5000 until end of turn.
