Ehh...I kind of agree with GreatChikorita, Tail Flip is perhaps a bit too strong, although the 50HP keeps it from becoming haxxy overall. As I recall, the old Geodude's Rock Blast (Flip a coin until you get tails, 10 damage times the number of heads) had an energy cost of 2, so maybe raise the cost and/or remove the 10 non-flipped base damage? That aside, the art is very nice and proffessional-looking, good job on that. Oh, and the 'Twitch' move is a nice touch, I think. Energy cost seems allright too. Overall, a very nice little card. ^^
