Swellow

Mid-air Crush: Choose 1 of your opponent's Pokémon. This attack does 20 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Flip a coin. If heads, your opponent discards 1 Energy card, if any, attached to that Pokémon.

Nosedive (40): Flip a coin. If tails, Swellow does 10 damage to itself.
