Mysterious Fossil [Mystery of the Fossils]

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