Soul Rinsing Spring of Dragons

Play this with [COST][Counter-Blast 1] if you have a vanguard with "Leuhan" in its card name! Choose up to two normal units from your drop, choose a card with grade less than or equal to your vanguard from among them, call it to (RC), and put the rest on the bottom of your deck in any order. That called unit gets [Power] +5000 until end of turn.
