Choose 1 card in your hand and shuffle the rest of your cards into your deck. Then, draw 4 cards. (If this is the only card in your hand, you can't play this card.)

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.
