dude, this is a bad card, but not at all because of the concept, but because if zanzarino updates this card into the game, would the design of the card mean the effect comes first and then the quanta cost??? because that would just kill you then. not a bad card, but if it gets implemented that way, definitely a bad card. but besides that, I see no problems at all.
EDIT: lol I know that it wasn't going to be implemented that way was just saying it would be VERY lolsy if it got implemented that way, lol and just a idea, this would seem to be a cool card if a god uses this card, a god of earth, but he uses stone skin when he gets to like 100 or less health.
