>>30292171Are you in-game or looking for a PvP Toxapex?
In-game, it's default ability Merciless is the best as it will quicken the pace of a fight by amplifying Tox's meager offenses. For PvP Regenerator is best.
In-game, your main win-condition will be poisoning the enemy and then hitting them with a Merciless-boosted Venoshock.
Toxic/Toxic Spikes/Baneful Bunker
Venoshock
Scald/Surf/Liquidation
Ice Beam/Recover
Toxic is the most reliable way to poison; Baneful Bunker has the most overall utility but requires prediction of unpredictable enemy AI. Toxic Spikes has the most potential in a single turn but a variety of pokemon are immune/neutralize it.

Look through this smogon discussion thread for a variety of PvP builds. Due to the nature of PvP there is rarely a "single optimal build," but instead different builds complement/counter different pokemon. Remove the spaces in the link.
