Fossil Egg (neo2-72 First Edition) is a Trainer card from the Neo Discovery expansion that can put an evolution of Mysterious Fossil onto your Bench and is treated as a Basic Pokémon. You flip a coin and on heads you may either search your deck for such an evolution to bench or place one from your hand, shuffling if you searched. This card cannot be played if your Bench is full, making bench space a key consideration when using it.
