Ressurection butterfly

Create an X/X Ghost token flying, hexproof
Deathtouch, Indestructable, and trample
at the end of each of your turns, place a -2/-2
counter on this token, when this token is a 0/0
or less, you lose the game
in that instant, the Ayakashi bloomed, and with even
a fraction of it's power unsealed, the world trembled
