Fossil Egg (Neo Discovery 72/75)

Rules

Flip a coin. If heads, search your deck for a card that evolves from Mysterious Fossil and put it onto your Bench or put a card that evolves from Mysterious Fossil from your hand onto your Bench. Either way, treat the new card as a Basic Pokémon. If you searched your deck, shuffle it. (You can't play this card if your Bench is full.)
