Politoed

Whenever three or more of these get together, they sing in a loud voice that sounds like bellowing.

Poke-POWER — Leap Frog: Once during your turn (before your attack), you may choose a Water Pokémon on your Bench and switch it with your Active Pokémon. This power can't be used if Politoed is affected by a Special Condition.

Big Chorus (30×): Flip a coin for each Water Pokémon you have in play. This attack does 30 damage times the number of heads.
