Darkrai #DP24

Search your deck for a Stadium card, show it to your opponent, and put it into your hand. Shuffle your deck afterward. If there is any Stadium card in play, discard it.

Search your discard pile for 3 Pokémon, show them to your opponent, and put them on top of your deck. Shuffle your deck afterward. (If you don't have 3 Pokémon in your discard pile, this attack does nothing.)
