The dubious disk will evolve porygon2 into porygon-Z when traded with it.

like the guy said it's best to just keep it untill you get the natiol pokedex. It's part of the Proygon trade eveloution line:
Porygonn+upgrade(trade wile holding)-->Porygonn2+Dubious Disk(trade while holding)-->Porygon-Z
It does nothing for unova pokemon.
