Omanyteオムナイト

Pokémon PowerFossil

Once during your turn (before your attack), you may flip a coin. If heads, search your deck for a card that evolves from Mysterious Fossil and put it on your Bench. Shuffle your deck afterward. Treat that card as a Basic Pokémon. This power can't be used if Omanyte is Asleep, Confused, or Paralyzed (or if your Bench is full).

Flip a coin. If heads, the Defending Pokémon is now Paralyzed.
