Just a couple quick thoughts.
Piloswine to C+
With Mega Glalie gone, this things major niche is gone and it's now once again outclassed, with it's main niche being what now, Ice Shard to pick off Lilligants and stuff? There's just really not much reason to use it over stuff like Rhydon and Steelix and Seismitoad now for SR. Certainly not on the same level as Cryogonal and Klinklang as viability, to say the least.
Volbeat to D
It has prankster weathers, and that's literally it's entire viability. Is there even any real major reason to use this over mons like Liepard 99.9% of the time?
Grumpig to C
There are better fire spam checks and it does little damage to M-Rupt who just 3hkoes it with earth power anyways. Things like Mantine have also seen a rise in usage and they are quite frankly more useful than this mon, and M-Rupt now also exists as a fire spam check. It has niches, but there are just much better mons to use at what it does. M-steelix is a free switch-in as well, the worst it can do is like whirlwind it. With Slurpuff gone, dark types have risen, and between that and getting icicle crash + knock off, Sneasel's much better. ORAS really did Grumpig no favors, as nothing in this meta really is going for it.
Lickilicky to C
Not that mega audino is an amazing cleric, but it outclasses this mon with a fighting neutrality, dark resist, and better stats. Can't say lefties, dragon tail, and a stronger attack stat seems like the better choice, and considering you don't have to mega evolve audino you can also use regen if you want with normal and have the best of both worlds. Already often outclassed by normal audino because of regenerator, but now, is there really much reason to use it?
Kricketune to C
Yes, it's the best sticky webber in the tier. Doesn't mean much when sticky web isn't even that good right now, (and while Pawniard has gotten worse, Malamar has gotten better) and the other setters are all bad too. Loses to Archeops and fast Qwilfish with taunt, and only gets up web or gets taunt off vs Crustle and Rhydon, and it still doesn't do much outside of web outside of like taunting things.
Masquerain to D+
Quite frankly, it's trash. Garbage stats, and thanks to those garbage stats, usually fails to do anything outside of Sticky Web. Maybe get like a scald burn or something if you're lucky. It's got quiver pass, sure, but it's so frail even with intimidate and has quite a few weaknesses, so it's not very likely at all to ever even get off the pass. And again, web isn't even very good right now, and Malamar's just able to use it against you anyways. Doesn't deserve to be in the same rank as Leavanny, which can at least do something with leaf blade/storm and magic coat, as well as an actually decent speed stat.
Accelgor to B
It's still a good spike setter, still has decent offensive options, and still is extremely fast. Nothing's really changed to make it unviable. It gets energy ball, focus blast, and encore, has 100 base special attack and it outspeeds everything relevant that isn't scarfed
Crustle to B+
Crustle still does it's job well also, stacking hazards. Yes, there are things that stop it, but it's still the only HO lead that sets both hazards, it gets to free it's item slot for mental herb, red card, or even more gimmicky stuff like power herb + solarbeam, and it still has a nice tool in stab rock blast. It's still one of the best at what it does and still manages to get up hazards well.
