Play Mysterious Fossil as if it were a Basic Pokemon. While in play, Mysterious Fossil counts as a Pokemon (instead of a Trainer card). Mysterious Fossil has no attacks, can't retreat, and can't be affected by Special Conditions. If Mysterious Fossil is Knocked Out, it doesn't count as a Knocked Out Pokemon. (Discard it anyway.) At any time during your turn before your attack, you may discard Mysterious Fossil from play. You can put Pokemon that evolve from Mysterious Fossil on this card.
