Okay a bit early but as two of the teams I used had Prim or Gyara on it and I don't feel like making more for just another day, my thoughts:
Tried two Tox sets this week. The second set was standard Specs. Not a whole lot to say about it. Hits very hard, but locking yourself into Normal, Poison, or Electric moves invites free switch-ins.
The first set comes from the Next Best Thing thread in the OU forum: AV Tox. Tox's typing gives it resistances to three prominent (special) offensive types: Electric, Grass, and Fairy as well as the less common Bug, Poison, and Flying. That base 70 SpDef isn't doing any favors though. Giving it an AV brings you up to a decent 265 SpDef, which means you can use Tox as a check to things like Roserade, G-Weezing, and even Gardevoir in a pinch. Another nice thing is AV bluffs a Choice item, so you can potentially nuke something like a Mamoswine on the switch with Boomburst predicting another move. The downside is this lacks in power compared to Specs or Expert Belt, so it's questionably viable, but hey.
squad
Other gimmicks I considered included Nuzzle and mixed Drain Punch. Tox's counters would be better off Burned or Toxic'd instead of Paralyzed so it's likely a very niche option. And Drain Punch does bupkis even with +1 so lmao don't even bother.
I never got around to Necrozma
