Seems overpowered, IMO. As Seiya mentioned, there is no way to kill the creature without a shield. The only two shields that can kill a creature are Thorn Carapace, Fire Shield, and of course, the respective upgraded versions of each card. Load a deck up with Deflagrations or Steals, and it entirely cuts out the need for Quintessence or immortality in general. Monsters would be untouchable. Personally, I don't like the idea of this card becoming a reality unless changed (big time), but that's just me. I like your humor in the card description though. Made me chuckle.
