im a sheep and its nom time
if we dont lose it,

> A/A+
I really like having toxicroak around. It makes Basculin feel trivial since the basc guys haven't switched over to double edge. Idk the odds of us keeping croak but I'm hoping for the best. It's got ZU's favorite physical attacking profile of Fighting/Poison and then Knock Off and Sucker Punch to boot, and it has set diversity with special sets, different items, and other options like SD and EQ. It's a fantastic mon.

A -> A-
It's not Toxicroak. The speed tier is useful, but I've been punished for not outspeeding Whimsicott in this meta one too many times to say that you can get away with this as your fastest mon. The other fightings just offer more, with Croak's real ability and top's spin.

A- -> B+
I think that pass being the slowest scarfer makes it usually not worth considering, especially when Hitmontop and Toxicroak are better fightings. On top of that, it's probably the worst tera dark user of our fightings since you probably would want to be Tera Poison, since it doesn't get STAB on gunk shot. The only niche it has over the other fightings is U-Turn, and I don't think that can keep it in A-, especially alongside possible scarfers like Grafaiai and (it barely counts but) Braviary.
I think there's a solid argument to put both Pass and Sneasel in the same tier, since I weigh their pros over Toxicroak similarly, but if Sneasel is higher because it's more versatile I see it.

A -> A-
I'm trying really hard not to hate on Mowtom too hard, but it doesn't typically beat Basculin and I think that's a problem. You kinda need a grass type that's able to do that in my opinion (or Toxicroak). I haven't used Mowtom much since Venu dropped, which is mostly due to the Basc MU + being resisted by Venu. Now, the fact that I haven't used it is why I'm not sure if I'm underrating it or not, but I still don't think too highly of it.

B+ -> A
If you haven't lost to a Sableye or ran/clicked Tera Dark on something for the Prankster immunity, I don't know what you're doing unless you have never used a fighting type/physical attacker in this tier or smth. Sableye is a viable piece of the meta, and is way more legitimate than the rest of B+ and most of A-. Will-o-wisp makes it a viable Spinblocker since you force out Hitmontop, and if the top player tries to be smart and clickes Taxel on the switch, they don't 2HKO you unless they dodge wisp or use tera.

A -> A-
Now that spinblockers exist, Sandslash is a really mid spinner. It's best used as a Gunk Shot resist that can threaten a knock, since it doesn't beat the ghosts (Sableye/Spiritomb), although its not like they want to take a knock. You can't deny Sandslash's utility which is why I think it should only go down 1 tier, but it's better as a physical wall than a designated spinner. Also, I don't like

A- -> A
Its death was greatly exaggerated. Turns out, adding Venusaur to maybe 2 fairy resists doesn't suddenly make Fairy a bad type to spam.

keep them where they are (A/B+ respectively)
I think these 2 are fine where they are. If you're disappointed with Lanturn, you're probably not switching into a Zard/Jolt and slow pivoting out immediately into your revenge killer, or are doing it at 50% HP. At least in my experience with Lanturn, it's able to do this as many times as you need it to in a battle when you keep it healthy enough. As for Orthworm, it has it's MUs. The only downside with it is its fighting weakness. Steel has its problems as a typing in a tier where Fire/Water/Fighting/Dark/Electric are some of the best offensive types, but between its stats, weight making it a relatively safe Snorlax switch-in, ground immunity, and access to spikes, I think its benefits outweigh its awkwardness and justify it in B+.
I don't really have an opinion on most of the UR noms, outside of what I already said about Samu/Ursaring being ranked. Feel like most of them need more showings, but they're all mons I'd consider using outside of the red Lycanroc, who is just Mabo with a worse defensive typing, and Clefairy, since idk why you would want a poison weakness on your fight resist.
