Flip 3 coins. Choose a number of your Pokémon in play up to the number of heads. For each of those Pokémon, search your deck for a card that evolves from that Pokémon and put it onto that Pokémon to evolve it. Then, shuffle your deck.
This attack does 20 damage to each of your opponent's Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Switch this Pokémon with 1 of your Benched Pokémon.
Look at the top 5 cards of your deck. You may attach any number of basic Energy cards you find there to 1 of your Pokémon. Shuffle the other cards back into your deck.
