I'm pretty sure FGs need a minimum of 60 cards in a deck (at least, I haven't seen any with fewer). Right now yours would have 30, which is half that amount.
BTW, thanks ratcharmer and AngelSpirit for testing my deck.
EDIT:
New FG, with the working name Firedrake.

Doesn't seem very difficult at all, he only used Sky Blitz once out of three matches, which was supposed to be his "gimmick". AM screws that strategy up...I may make a different version after other flaws are discovered.
