Playablity: I don't play the TCG that much (Only TCGO) but I'd say it's pretty good. INTENSE INFO FOR REVIEW! I RANDOMLY GENERATE NUMBERS FOR RATINGS!
Giga power: Very good move, it is useful for the next move. Very useful, it is obvious as when it does 20 damage to self, it increases the next moves power and the move itself. With aspertia, it is a deadly combo. 4/5
Raging hammer: For 4 colerless energy, it is a pretty decent move. With DCE it is a great card, but without it it'll takes as long as it's ability in-game to be useful. While it does +20 damage for each time Giga power is used, it is pretty bad. 3/5
Colors/photo: Horrible and I mean horrible for a pokemon's photo. The texture looks bad, and regigas is so boring. 1/5
Well, see you guys on the next CoTD!
