Pokémon / Misty's Psyduck

Flip 3 coins. If exactly 1 is heads, draw a card. If exactly 2 are heads, this attack does 20 damage. If all 3 are heads, choose 1 of the Defending Pokémon's attacks. Misty's Psyduck copies that attack except for its Energy costs. (No matter what type the Defending Pokémon is, Misty's Psyduck's type is still Water.)
