Old Trees and Johannhowitzer both made wonderful points, if you have 100 purify counters, and your opponent had 100+ damage on the field, you still die. And by the time you even get 100 purify counters, most decks would have you dead long before then. I agree it is UP now, so reduce the ability cost by 1 and buff the attack by 1. I can see a very nice anti-scropio deck being made with this card. Hell, I can even see a whole new set of anti-poison decks with this card.
this card will have some decent art by the end of the month, look forward to it.
