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 or your discard pile for a Trainer card that has Fossil in its name or a Stage 1 or a Stage 2 Evolution card that evolves from a Fossil. Show it to your opponent and put it into your hand. If you searched your deck, shuffle your deck afterward.
