==Play Helix Fossil as if it were a Basic Pokémon. While in play, Helix Fossil counts as a Pokémon (instead of a Trainer card). Helix Fossil has no attacks, can't retreat, and can't be Asleep, Confused, Paralyzed, or Poisoned. If Helix Fossil is Knocked Out, it doesn't count as a Knocked Out Pokémon. (Discard it anyway.) At any time during your turn before your attack, you may discard Helix Fossil from play.==

When this card is discarded from play, your opponent discards the top card of your deck.
