Slowpoke & Psyduck GX #217/236

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 Water 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.)
