Search your discard pile for 2 different Trainer, Supporter, or Stadium cards, show them to your  opponent, and your opponent chooses 1 of them. Put that card into your hand, and discard the other  card. (If all Trainer, Supporter, and Stadium cards in your discard pile have the same name, choose  1 of them. Show that card to your opponent, and put it into your hand.)

You can play only one Supporter card each turn. When you play this card, put it next to your Active  Pokémon. When your turn ends, discard this card.
