Definitely disagreeing with both the Infernape and Salazzle noms. For the record, I'm all for Infernape rising, but to B+ is just way too drastic and it also isn't good enough lol.
Here's my problem with your Salazzle nom
BlackMalachite - you talked up all of Salazzle's upsides big time. Fire/Poison coverage isn't bad by any means, but also isn't necessarily amazing when Mega Aerodactyl is absolutely everywhere. Salazzle also has NO coverage bar Dragon Pulse (which only hits things like Latias and Zydog) and Hidden Power (lol) to complement its impressive Special Attack. It also faces immense competition from Infernape, which by virtue of its Fighting-typing and Stealth Rock neutrality, is an infinitely better check to Bisharp, who still pressures the out of Salazzle with Sucker Punch, which OHKOs after Stealth Rock. It also almost never has room for Encore or Disable since it NEEDS coverage, and its also heavily pressured by super common threats in Scarf Krookodile, Zygarde 10% and Mega Aerodactyl. Overall, the main reason to keep Salazzle in C is the fact that Infernape is almost always better as a Nasty Plot user and checks all of the threats you mentioned bar Clef way more reliably.
Speaking of Infernape, the nom for its rise is way overblown as well. Infernape does NOT deserve a rise as drastic as two sub ranks. For one thing, your calcs are all of Pokemon hit super effectively by Infernape's attacks. Of course they're going to be OHKOed and 2HKOed by its attacks, they're weak to them. Infernape also never has room to fit all of that coverage in one set, it usually isn't even carrying Gunk Shot since it values Stone Edqe and EQ way more. You also say that Volcanion fails to properly pressure dark types, but OHKOs Krookodile and Bisharp with its STABs and bops Hydreigon and Mega Absol with Superpower. Infernape's main reason for currently being in B- is because of the meta's general unkindness to it. Alakazam, Starmie and Latias either hardwall or just remove Infernape, and Gliscor and Primarina are two big problems for it too. Infernape still has its uses, its the playdough of UU with arguably the most viable sets of any mon in the tier, and has lots of ways to break past checks, like Scarf U-turn, but is so hurt by 4mss and the prevalence of its checks that can't all crumble to the same coverage means that its more deserving of a rise to
B instead of A.
Oh, and absolutey supporting the noms to rise Alomomola and Amoongus and to drop Toxicroak. Alo's just an amazing bulky pivot that can heal both itself and teammates in one turn and absolutely scoff at non super effective attacks. Amoongus currently forms the tier's best defensive core with Hippowdon and is just such an effective bulky pivot, status spreader and switch-in to a plethora of top tier threats. Toxicroak hasn't had nearly as much traction in terms of support for its drop, but its main use was as a rain check, and with both rain and azu gone and plenty of Water-types (Prima, Starmie, Swampert, Volcanion) that carry coverage that hits it super effectively, Toxicroak isn't really a reliable check to non defensive water types. Its only sets are also either NP or SD, which both face competition from other fighting types in Infernape and Cobal who either have the bulk necessary to set up or the speed to actually outpace their checks, which are two things Croak lacks.
