Honestly Sneasler doesn't seemed at all suspect worthy if Dire Claw didn't exist. My predictions about it being to get past its checks with Poison Touch CB sets were inaccurate due to the abundance of good poisons in the meta, and while the Unburden sweeper sets are threatening, it struggles to find coverage for everything, has a lot of midgame stops, and can't always find opportunity to setup. Dire Claw lets it do what I predicted Poison Touch would do- break its checks with a bit of luck. Furthermore, Sneasler isn't strong enough to be able to power through even offensive resists to its moves, which it will always have. Dengo, Corv and Lando beat it 1v1 whatever set, Slowking and Pex beat anything that's not TB ground, and literally all the other OU poisons barring Clodsire beat its CB sets. I'm hoping that Gamefreak gives something else Dire Claw so we can ban the move instead because I think Sneasler will actually be a healthy addition to the tier but unfortunately that probably won't happen. Definitally ban the mon with the move though, Dire Claw allowing it to beat literally anything with luck is unhealthy.
Now I don't really agree that it has lots of checks, especially checks that can chek every set it can potentially run
I think it has ways to get around corv and lando tho, especially with grassy seed plus terrain
for corv I don't expect you to run a lot of attack evs anyways, so brave bird doesn't do a lot factoring in grassy seed defense boost. so if you switch your corviknight in the turn sneasler swords dances, it can swords dance again, live a hit, and OHKO with Close Combat.
Now for lando, I mean 1.5x defense plus grassy terrain really hinders earthquake's damage output, so again it can ALSO live a hit and return fire after 2 swords dances, again OHKOingyour supposed check to sneasler.
Tox just feels too passive and sneasler can just set up on tox really, especially when grassy terrain boosts it's longetivity
It's also a great tera user, with tera flying to boost it's acrobatics damage output, as well as avoiding OHKOs from certain attacks
Only options of actually walling it rom what I observe is unaware users like dirge or clod, but I think clod isn't really that reliable tbh.
and also keep in mind sneasler is made to be a lategame cleaner. it's not supposed to start sweeping when its checks are still healthy and only once they're sufficiently chipped, which honestly isn't too hard to do.
and also I don't really agree with it not having enough coverage to an extent that it can be easily walled, close combat + acrobatics + shadow claw/fire punch is pretty scary already when it's +2 or potentially +3 if you put corv or toxapex in front for it to setup and +2 in speed from unburden as well. Not to mention it can slot in gunk shot or his famous rng move in to potentially get rid of checks such as Zapdos, which would otherwise wall the set I mentioned just then. It definitely has enough coverage, it just has to forego 1 or 2 attacking types, but generally doesn't affect it too much lol
While priority may seem to be a way to get rid of sneasler, most priority attacks are physical, and that's partly why the grassy seed defense boost is so valuable. While you could argue it's still possible to pick off a weakened sneasler with kingambit sucker punch or whatever, sneasler would still probably have taken down like half of your team as you try to chip it into priority range. That is assuming you have a strong priority attacker like Kingambit lol. If you don't tera, which you really don't have to most of the time because your damage output is very high anyways - also another advantage of the unburden set - then it's fighting typing is also quite useful in resisting sucker punch, which is usually the strongest form of priority.
I'm aware I don't have any calcs supporting what I pointed out - since I'm too lazy :) - so feel free if u wanna calc it to see which checks really do work. Most of what I say is based on my experience using rillaboom + sneasler
