Nice art to play on the gluttony but wouldn't that fit Snorlax more? Anyway.
Considering most Fighting cards aren't as used as much as the elementals, I wouldn't worry too much about that. Amnesia and the high HP makes a decent wall and with the right cards (Lum Berry), you can circumvent the sleep status of Lazy Headbutt. Compared to some Colorless evolutions, this certainly has potential.
6/10. With the right cards, 8/10.
