Wow, a reprint of that old Skyridge (I think, might have been Aquapolis though). Its hard to say how good this is gonna be, but it certainly could see some use as long as Shaymin in the format. Other than that however, for this card to really be good, there needs to be some draw-power that does NOT come from supporters. I do though, really love the art on this card, that's something that will never get old despite how much the metagame changes. I wouldn't be surprised to see it used in Typhlosion though, as its a guaranteed 160 damage.
EDIT: Skyridge Oracle, that's which supporter it was.
