Dome Fossil (Arceus 92/99)

Rules

Play Dome Fossil as if it were a Colorless Basic Pokémon. (Dome Fossil counts as a Trainer card as well, but if Dome Fossil is Knocked Out, this counts as a Knocked Out Pokémon.) Dome Fossil can't be affected by any Special Conditions and can't retreat. At any time during your turn before your attack, you may discard Dome Fossil from play. (This doesn't count as a Knocked Out Pokémon.)

Abilities

When you attach a Fighting Energy card from your hand to Dome Fossil (excluding effects of attacks or Poké-Powers), search your deck for a card that evolves from Dome Fossil and put it onto Dome Fossil (this counts as evolving Dome Fossil). Shuffle your deck afterward.
