Swampert PRC 36

When you attach an Energy card from your hand to this Pokémon (except with an attack, Ability, or Trainer card), you may attach 2 Energy cards.

Once during your turn (before your attack), you may search your deck for a card. Shuffle your deck, then put that card on top of it.

This attack does 30 more damage for each Energy attached to this Pokémon.
