K so let's talk about some (somewhat) easy moves I'm seeing.
Dodrio to C+
Seriously this mon does not belong in C- in this metagame. Hits harder than Swellow with CB, has access to pursuit and knock off, has few switch-ins, cleans teams easily with base 100 speed, has very few switch-ins w/ band (aside from bulky steels and rock types, and crodino bc crodino is bulky af[only physical attacker that ohkoes it unboosted is banded dragalge lol] nothing wants to switch into this), forces a ton of switches it can abuse with said pursuit, and it doesn't need a turn to set-up an orb and isn't taking orb recoil every turn. It's devastatingly powerful and also utilizes one of the best offensive typings in the game in flying(flying types are so good in this tier rn too). Even if it suffers with some competition with Swellow, it still has many niches it can shine in. Also yes, Swellow does learn Pursuit, but not only does CB Dodrio utilize it better and hit harder with it, it doesn't have to drop an important move to use it.
Some quick calcs(nice 10% difference on the same move in Dodrio's favour)

Have I mentioned that this thing can also run other sets? Sub endeavor, scarf, sharp beak, heck, wp endure flail. This thing's got a lot of untapped potential imo, and it's certainly a lot more effective than Metang or Volbeat..
Golem to C+
Custap's back, this thing has some actual niches now and isn't completely outclassed by Rhydon. Do I really need to explain this further?
Muk to B-
With (Mega) Steelix (and Qwilfish I suppose), Muk has gotten a lot more effective. Both band and av sets work well for it, as base 105 attack + gunk shot is nothing to sleep on, and hits like a truck, plus Muk also has solid coverage and a priority move. Poison Touch is a great ability and helps Muk to whittle down any switch-ins that aren't poison/steel type *cough* Rhydon and Seismitoad *cough*, while it's great special bulk allows it to sponge a ton of hits already, plus with av it becomes a specially defensive god.

It also kind of destroys Crodino with both sets, which is nice. Even if it does struggle with certain mons, depending on what moves/set you're running, it can bop a lot of things you might not expect.
252+ Atk Muk Explosion vs. 252 HP / 0 Def Mega Camerupt: 257-303 (74.7 - 88%) -- 6.3% chance to OHKO after Stealth Rock

0 SpA Muk Giga Drain vs. 252 HP / 4 SpD Quagsire: 216-256 (54.8 - 64.9%) -- guaranteed 2HKO after Stealth Rock and Leftovers recovery
Not to mention resistances to common grass and fighting moves and a nice gg to lilligant.
Also to start some discussion because I doubt anyone cares much about 3 mons nobody uses, what would you guys think about Uxie, Kangaskhan, Hariyama, or Mega Audino to S rank?
Uxie, while perhaps not as versatile as it's sibling legend Mesprit, can run a variety of sets, sponge a variety of hits, and provides tons of support for teams. Offensive CM, Sub CM, screens, sr, physical defense, you name it, an uxie can do it. U-turn's also really nice for grabbing momentum and things like T-wave or Knock Off can help it to wear down and cripple the opposing team.
Kangaskhan was S rank for a reason back in XY, and with even normal steelix out of the tier, it's probably better than ever. It hits like a truck with double-edge, has very few safe counters because of the amount of coverage moves it gets(fire punch, drain punch, aqua tail, and earthquake bop tons of stuff), has dual priority to revenge tons of stuff, and also has decent bulk. Scrappy is an amazing abillity, allowing it to smack all but two types neutrally with it's powerful double-edges. It can also even run an av set effectively.
Hariyama is indisputably one of the most important and one of, if not the most common NU mon out there. It's by far the best user of av in the tier, by far the best fire stop in the tier, and probably the best tank in the tier too. It stacks up well against common mons like Typh/M-Rupt, gets a bunch of useful coverage moves(knock off, eq, heavy slam, thunder punch, etc) to beat a ton of switch-ins, beats most of the special attackers in the tier, has priority, hits decently hard with 120 attack and close combat, and is probably one of the easiest mons to place on a team in NU. It does it's job very well, and despite being somewhat one dimensional in this role, can also run a few other tricks, such as cb or guts, to bypass things that would normally be problematic for standard hariyama. Hariyama is a crucial part of the NU metagame, and it quite simply works well. To quote the S rank description, "Reserved for Pokemon who can sweep or
wall significant portions of the metagame with little support". Sounds like what an AV Hariyama does to me.
Mega Audino, cited by most as by far the worst mega at the beginning of ORAS, and expected to be NU by about everyone as soon as we heard it had Healer. That being said, it is in no way, shape or form bad. Not only does Audino have surprise factor, it is all but unkillable in it's standard Crodino set. Have I mentioned that the only unboosted physical attacker that OHKOes it is CB Adaptability Dragalge? Aside from the typical Crodino you can do things like wish cm, cm 3 attacks, heck you can probably run a decent wishpass set thanks to how bulky Mega Audino is, and only mega evolve when you need the bulk. It certainly has a fair sure of checks in steel types and poison types, but it's still a major threat to most teams and can take advantage of a lot of pokemon to start dropping some calm minds and devastating teams.
