Jolteon

Poke-POWER: Undevelop

Once during your turn (before your attack), you may devolve Jolteon and put Jolteon into your hand. This power can't be used if Jolteon is affected by a Special Condition.

Flip a coin. If heads, this attack does 10 damage plus 30 more damage.

If Jolteon evolved from Eevee during this turn, this attack does 10 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
