Flip a coin. If heads, search your deck for up to 5 Grass Energy cards and attach them to your Pokémon in any way you like. Then, shuffle your deck.

This attack does 30 damage to 1 of your opponent's Pokémon for each Grass Energy attached to this Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
