(This doesn’t count as a Knocked Out Pokémon.)

Once during your turn (before your attack), if Omanyte is in your discard pile, you may search your discard pile for Omanyte, reveal it, and put it onto Helix Fossil (this counts as evolving Helix Fossil).

The fossil mechanic is... clunky at best. I think it was at its best in this era, with Fossils that could help accelerate the Pokémon, and they all worked together. I also tried to make Omastar a little powerful to compensate for the overall clunkiness of getting it into play (And that trainer lock kinda ruins this)
