Look at the top 7 cards of your deck, choose 1 of them, and put it into your hand. Put the other cards back on top of your deck. Shuffle your deck afterward.
Choose 1 of your opponent's PokÃ©mon. This attack does 20 damage to that PokÃ©mon. (Don't apply Weakness and Resistance for Benched PokÃ©mon.) Then, remove from Manaphy the number of damage counters equal to the damage you did to that PokÃ©mon.
