Any Sneasler set that actually uses it for its kit beyond the Match-up/Noob Bait that is Dire Claw gets a thumbs up from me. U-Turn Poison touch is interesting because it turns one of Sneasler's bigger issues (breaking past the tier's typical Bulky Pokemon) into both a momentum grab and a chance to wear several answers down itself. With Toxic having seen a massive reduction in users, normal Poison has a bit more breathing room as the "Passive Damage" status, at least to the extent of being a benefit instead of "shoot now I can't Toxic/Burn them" if it procs on most teams. Not sure if Fake Out is that big a deal but U-Turn with Poison Touch definitely seems like it could yield results as an early-mid Game pivot with cleaning potential for late-game.
Among things that could switch reasonably into Sneasler's STABs, Great Tusk, Bax, Dragapult, Zapdos, Zama-Hero, Moltres, Tera'd Ting-Lu and Lando-T all definitely hate the idea of Poison Chip from the regular hits, much less from the turn in which they already got read and were pivoted on. It's also less than welcome on Gholdengo and Dondozo, who don't like being pushed to sink momentum into a recovery turn any sooner than they can possibly stretch to.
The two biggest thorns in Sneasler's side with a set like this are Amoongus (Gunk Shot is a 25% chance to 2HKO without Hazards from full, nothing else touches it) and Glowking (no surprise there), but KOing everything isn't the job of a Pivot set anyway and any good team in this OU needs something to hit Poison types and ESPECIALLY Glowking.
