You may discard a card from your hand. Then, draw cards until you have 6 cards in your hand. (If you can't draw any cards, you can't play this card.)

Card rule

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.
