Slowpoke & Psyduck-GX UNM 35

Discard any number of Supporter cards from your hand. This attack does 40 damage for each card you discarded in this way.

Flip a coin. If heads, this attack does 100 more damage. If this Pokémon has at least 6 extra Energy attached to it (in addition to this attack's cost), flip 10 coins instead, and this attack does 100 more damage for each heads. (You can't use more than 1 GX attack in a game.)
