Since the post relating to the last update reads that we can discuss the rises / drops, I'm going to share my thoughts on the ones I disagree with :
: Seeing that Tomohawk dropped (which in my opinion isn't deserved, but I'll cover that later) and that many Ghost and Psychic-types like Necturna, Pajantom and Alakazam rose makes me even more confident that Colossoil should have stayed A, as even if Weavile is more suited to pursuit trap Necturna and Pajantom due to its better Speed and more reliable priority in form of Ice Shard, I think that Colossoil is still the second best Dark-type in the tier, only behind Greninja which accomplishes completely different tasks. Being worn down "very quickly" when holding a Flame Orb is an over-exaggeration to me, at least it never has been an issue in my experience, especially since Colo packs a resistance to SR, and any Life Orb user will often die much more quickly, Weavile being a prime example. The Flame Orb set is never a deadweight in any match-up due to its very strong Sucker Punch which threaten some of the most dangerous Pokemon in the metagame, including Aurumoth and just about any fast Pokemon that doesn't resist it, Facade variants barely has any reliable answer as even Tomohawk can lose if you predicts Roost correctly, and Pursuit is extremely useful against a lot of Pokemon, especially the ones that tend to rely on statues like Chansey. Scarf Colo is also pretty neat since its a reliable RK to Aurumoth and Cawmodore when packing Foul Play, and you don't have to rely on Sucker Punch anymore to threat Pokemon like Pajantom and Alakazam-Mega before using Pursuit.
: Being "good" in a viable archetype doesn't warrant B since the Pokemon itself is still pretty niche in my opinion and Fidgit already covers some Magearna and Koko variants very effectively. Mawile-Mega's typing, Sucker Punch and wallbreaking capabilities will certainly be missed since Camerupt has an hard time against Lati@s-Mega, Arghonaut, AV Colo, SpDef Pajantom and Zygarde, Gastrodon, Rotom-W... Even though it still hit them hard, it will have to flee more often than Mawile, and thus will make its team lose more TR turns.
: Unlike Alakazam-Mega, Stratagem doesn't consume a mega-slot, isn't weak to Pursuit and even though it doesn't have the luxury of a perfect coverage with 3 moves, this is only annoying if you don't have anything else to carry Stealth Rocks, and with 4 attacking moves Stratagem hits a much wider array of Pokemon, including some that gives trouble to Alakazam like Celesteela, Magearna, AV Tangrowth, Sableye-Mega... It also doesn't have to rely on an inaccurate move like Focus Blast, and while Alakazam-Mega is very powerful, there's a lot of Pokemon it cannot threaten to OHKOsince it doesn't hit them super-effectively , like Offenisve Jumbao, Volkraken, Zard-Y... Besides, I think that Stratagem, Hoopa-U and to a lesser extent Zard-X are significantly more viable than the rest of B, so seeing these here feels very weird to me.
: You said it yourself: Cawmodore restrains teambuilding, something that doesn't apply to most of the B- Mons like Keldeo since you usually end up checking them without thinking about it. I think that the argument that reads that Cawmodore has an hard-time setting-up is just straight up wrong, as it can easily set-up in front of most variants of Jumbao, Arghonaut, Colossoil, Fidgit, Krilowatt, Kitsunoh, Ferrothorn, Kartana, Malaconda, Zygarde, Landorus-Therian, Plasmanta, Tapu koko, Tapu Bulu, Tangrowth, Clefable, Scizor-Mega, Gliscor... and the list goes on. So unless you're really confident that you'll be able to keep each of these Mon out of your teams or outside the field at the end of each turns, be sure to pack one of Hazehawk (which still has to leave the field at <40%), Cyclohm (with Fire Blast), Zapdos, Celesteela (with a spread and set specifically made to handle Cawmodore), Scarf Volk, (Ash-)Ninja, Scarf lele (HP Fire isn't a sure OHKO on 75% Cawm though) or something that has a niche on checking Cawm. Intimidate is also perfectly usable if the ability to set-up in front of Crucibelle-Mega or Ghostium-Z Pajantom, for instance. At least I never saw a Cawmodore that couldn't find the opportunity to set-up. It's otherwise very similar to Necturna which has admitelly less checks, more chance of to set-up and is more splashable and versatile, in exchange of an harder time to set-up and barely any defensive utility.
: Kerfluffle deals much more damages to the likes of Celesteela or Magearna than Tapu Lele with Focus Blast, which achieves a 2HKO with rocks on most variants on the former, Chansey shares the same fate. Tapu Koko in my opinion isn't really a good comparaison as an offensive-Fairy type, especially since it's much easier to check it than Kerflufle, which is also significantly faster than Lele. Parting Shot is a big selling point and is in my opinion very underrated in an environment in a metagame with a wide amount of dangerous set-up sweepers like Aurumoth, Necturna and Zygarde as well as Voluturn oriented teams are this good. Z-Celebrate was also very scary the few times I faced it on the ladder since there aren't much scarfer faster than Kerfluffle bar Greninja, which needs Gunk Shot to reliably RK it, and Tomohawk has to trade if it wants to stop it, whereas Circle Throw / Toxic less Arghonaut serves as a set-up fodder.
: I still that Tomohawk is an overall better Pokemon than Crucibelle-Mega and Zygarde and thus is worthy of S-Rank. I hardly doubt that the impact Hazehawk has on the metagame can be denied, especially when it checks the three current S ranked Mon in one slot (it admittely doesn't fair well against Subtoxic Zygarde, but why are these variants regarded as the most effectives one in CAP again ?). Being a set-up sweeper that can reliably threaten Tomohawk and Arghonaut is an advantage. It also makes a very good spinner due to its ability to threaten Necturna and Revenankh and progressively weaken most SR setters like Ferrothorn and Lando-T, and Prankster SR is also neat. Outside of all the utility it brings, Offensive Tomohawk has multiple reason to be chosen over Tornadus-T, with only two STAB (although their accuracy remain an issue, but Crucibelle-Mega has a similar problem but is still S rank) , it's usually tougher to switch into than a Tornadus-T with 4 attacking moveslot due to the additionnal STAB and power and much scarier to defensive oriented teams. This frees the two remaining moveslot with a lot of cool options like Roost, Taunt, Nature Power, Heat Wave ( for Kitsunoh and steels in general) or the wide array of utility moves it can bring. In my opinion, Tomohawk still excels at everything it can do, both dfensively and offensively, and should rise if it's going to move at all. Even if Psychic-types are rising, it doesn't prevent it from doing its job. It's too metagame-defining to be ranked lower.
I agree on everything other nomitions made bar rising Tangrowth, which in my opinion faces too much competition from Jumbao and the fact that it cannot check everything it wants all at once is kinda bothering. I may developp later, when the three CAP 25 join the party.
