Castaway is a Supporter card. It's part of the EX Crystal Guardians set.
|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.
Search your deck for a Supporter card, a Pokémon Tool card, and a basic Energy card. Show them to your opponent, and put them into your hand. Shuffle your deck afterward.
