I agree with the nom for Megachomp to B/B+. It definitely has a solid niche and thrives in a meta where balance and/or fatter teams are really common. There is no denying this mon is such a massive threat to the dominant playstyle, so B- is definitely underselling it. Also rofl at trash mons like Mega Beedrill, Mega Sharpedo, Mega Sceptile and Quagsire being ranked above it. I always see this "opportunity cost" to use Mega Garchomp because mega slot xD, yet these mons are ranked above. Wtf does Mega Beedrill even do, dies to any priority against offense, can't wallbreak through any fat cores and just about lacks enough power to pick up the KOs it needs (it's dying if it's not KOing something). Also has trash STABs with hardly good coverage to round it off (yes it gets Drill Run but that does zero to common Steels like Scizor, Ferro, Skarm etc). Idk how this mon's niche can even be ranked higher than Mega Chomp's. Quagsire is still ranked too high imo, it lost its best niche in beating Baton Pass and there are just better bulky waters to use. Mega Sharpedo requires a ridiculous amount of support (needs hazards, prior damage, wearing down checks etc) to even clean late game, and has horrible bulk. Unlike MegaChomp, Mega Shark needs support whereas MegaChomp just appreciates it. Sharpedo is hardly ever putting in work otherwise, other than getting a strong Crunch off or something before dying to a Tackle. I'd expand more but I just wanted to point out how it's ridiculous MegaChomp sits at B- while these mons are ranked higher. The arguments I see for keeping MegaChomp down can easily be applied to these mons so idk why they stay in their ranks. I guess people just forgot about them / don't care enough about the B ranks (everyone always looking at the A ranks). Anyway, I have a nom to make:
Dragonite B+ -> A-
Having used this Pokemon quite a lot to get reqs, I think it's pretty underrated imo. Dragonite is actually really good and can put in work against pretty much any archtype. Against offense, it's Banded Espeed is actually ridiculously good for cleaning up late game or revenge killing in general. I'm specifically a fan of the CB set, the immediate power it provides is fantastic for giving it solid niches in revenging and wallbreaking.
252+ Atk Choice Band Dragonite Extreme Speed vs. 0 HP / 4 Def Thundurus: 196-231 (65.5 - 77.2%) -- 18.8% chance to OHKO after Stealth Rock
This is gauranteed after Thundy takes a round off LO recoil (it's most common item by far). Thundy is really common on offense and just painful to deal with in general, especially if you're using offense yourself. Dnite gives you a good way to kill it without worrying about taking a T-Wave beforehand or just a strong LO Tbolt / HP Ice.
252+ Atk Choice Band Dragonite Extreme Speed vs. 0 HP / 4 Def Talonflame: 193-228 (64.9 - 76.7%) -- guaranteed OHKO after Stealth Rock
Talonflame, another big threat to offense teams is dealt with nicely by Dnite. You don't have to take a Banded BB to kill it, and you can tank it anyway with Multiscale.
Banded Espeed in general is just really good. It's a great answer to offense teams that need a way to deal with set up sweepers or need strong priority, and at the same time a Dnite slot covers a decent switch in to common threats like Keldeo.
Against fatter teams, Banded Outrage just breaks anything.
252+ Atk Choice Band Dragonite Outrage vs. 252 HP / 144+ Def Hippowdon: 231-273 (55 - 65%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Choice Band Dragonite Outrage vs. 252 HP / 232+ Def Slowbro: 226-267 (57.3 - 67.7%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Choice Band Dragonite Outrage vs. 248 HP / 216+ Def Rotom-W: 234-276 (77.2 - 91%) -- guaranteed 2HKO after Leftovers recovery
252+ Atk Choice Band Dragonite Outrage vs. 252 HP / 240+ Def Mega Venusaur: 207-244 (56.8 - 67%) -- guaranteed 2HKO
I think these calcs should explain that nothing that doesn't resist is walling this thing. It's a fantastic wallbreaker. And yeah it's true that Steels and Fairies can stop these, but most don't like taking one or two anyway.
252+ Atk Choice Band Dragonite Outrage vs. 248 HP / 0 Def Heatran: 156-185 (40.5 - 48%) -- 5.9% chance to 2HKO after Stealth Rock and Leftovers recovery
Heatran can't even do anything back either. Other Steels like Skarmory and Ferrothorn are threatened by Fire Punch and it has EQ for those who aren't. You can even run Superpower to lessen the 50/50s, if it even is that.
This is not mentioning its other sets, such as DD which is pretty great considering it has Multiscale, so it can set up fairly easily and put in work at the same power of Choice Band, but with Speed and being able to switch moves. Sp.Def Dragonite is also decent, albeit really rare now, but it just goes to show this Pokemon can be versatile.
TL;DR - Dragonite is versatile enough to be considered A- worthy, and packs a solid niche by giving offense a revenge killer, a wallbreaker, a ground immunity and a Keldeo switch in. It is indeed capable of picking up sweeps too with its DD set, and can belong on fatter teams with the Sp.Def set.
"Reserved for Pokemon that are fantastic in the OU metagame, and can sweep, support, or wall significant portions of the metagame. These Pokemon require less support than most others to be used effectively and have few flaws that can easily be compensated for when compared to their positive traits. These Pokemon exert a strong presence in the metagame."
With its DD set and stellar coverage (as well as Espeed to make reveging it harder), it is capable of sweeping a big portion of the meta. It's not so much a supporter but it can be with its bulky set, especially with access to things like Heal Bell. With regards to walling, well it's not really a wall but it is a decent switch in to a top threat in Keldeo. It doesn't really require support to do its niche for revenge killing or wallbreaking, but I guess trapping Steels with the classic DragMag core is nice to ease its job. It does appreciate Stealth Rock removal though but that hardly means much considering your team's gonna pack hazard removal 99% of the time anyway, and it has solid bulk to live the majority of hits after Stealth Rock. This is easily overshadowed though when you look at its positive traits. And yes I know it has flaws since common types like Steel and Fairy can be a pain to it spamming Outrage, but I feel this is a problem keeping it from rank A or A+, rather than pushing it down to B+. As said before though, it can definitely threaten said Steels and Fairies anyway. This mon is really solid but does have some issues holding it back, which is pretty much a perfect definition of A- rank.
