Wallbreaker Charizard X: This set allows Charizard-X to run all three attacks its other sets wish they could run while also having longevity, thanks to Roost. I think this set for Charizard X warrants A rank, since it can't boost its speed, and therefore isn't amazing v. offense.
Unaware Calm Mind Clefable: Tbh I'd never really use this. Because you lack Magic Guard, you're forced to run Heal Bell, and because you lack Softboiled, you're basically forced to run WishTect. This means you cannot run Flamethrower on the set, which allows Steel-types to very easily handle Fable. It does have its applications, such as walling special setup sweepers and then sweeping them, but a) it's flawed, for what I already said, and b) I'd rather use sr fable to make use of obvious switches. I think a drastic drop is warranted, even C+, since I'd really never use this.
Stealth Rock Clefable: This set on the other hand is godlike. It's easily able to switch into special threats like Greninja, Latios, Thundurus, set up hazards, and either act as a pseudo-cleric or damage steel-types with a decently strong fire attack. For its mixed defenses + not caring about hazards/toxic/burn, I think A+ is more appropriate for now.
Substitute + 3 Attacks Gengar:
Destiny Bond + 3 Attacks Gengar:
Taunt + 3 Attacks Gengar: I think all three Life Orb Gengar sets belong in A+. They all restrict its checks and counters greatly, and, in tandem with the standard three attacks, make it an absolutely pain to switch into.
Bulky Swords Dance Mega Scizor: Heatran + Slowbro are on the rise, and this set struggles against them. I'd say this set belongs in A now, and that...
Swords Dance + 3 Attacks Mega Scizor: This set, that handles Slowbro + Heatran + Ferro, is A+ worthy now.
Choice Scarf Excadrill: I'm Surprised this isn't ranked yet. It's a really cool revenge killer + spinner, and handles many of its checks + counters, some being Bronzong and Rotom-W, because it negates Levitate. I'm thinking A- for this, but I'm not really sure.
All-out Attacker Aerodactyl: This set lacks the longevity of the stallbreaker set, but is able to kill a lot more threats thanks to its excellent coverage. I'd say this fits better in B+.
Stallbreaker Aerodactyl: This set is able to break stall easily, thanks to its great 2 move coverage (Water/Flying) + access to Taunt and reliable recovery. It also checks Diggersby, which is amazing. Easy A-.
Specially Defensive Jirachi: This is a great set, thanks to its ability to handle Latios + Gardevoir superbly, and I think of it as a strong contender for A-.
Choice Scarf Jirachi: This set however struggles in OU, thanks to its mediocre speed tier (all scarfers should really be faster than 100 for charx) + inability to recover off the hits it's forced to take. I think it deserves to drop to C+, showing that it isn't terrible, but needs a lot of support.
Pivot Jirachi: This set abuses Jirachi's ability to beat the Latis in order to set stealth rock. It can pivot whenever a switch is obvious thanks to uturn, use its semi-strong stab attack in iron head, and either try to abuse paraflinching tactics with body slam or hit ferro and zor with Fire punch. This jirachi can't recover, but it makes up for this by setting sr. I think this deserves B+.
SubToxic Jirachi: This set is a pain to deal with, since bulky grounds, an easy Jirachi switch in, are forced to stay in to break the substitute, before which they are Poisoned. The set abuses its great typing and the ubiquity of Latios and Gardevoir to come in, set up a substitute, and watch the opposing team all get poisoned or flinched to death. The set also runs fire punch to handle ferro and scizor, two things that don't care about either Iron Head or Toxic. I think A- is possible for this set.
Mixed Jirachi: This set uses Icy Wind and Hidden Power Ground with an Expert Belt in order to lure some of Jirachi's best switchins, Landorus-T and Heatran. As usual, it also uses Iron Head, and often uses Fire punch for steels or thunderbolt for waters in the last slot. It can run so many different moves, but unfortunately can't run all of them. It also has no way of recovering, so I propose B- for this set.
Assault Vest Kyurem-B: This set is responsible for cube's rise to A- on the normal thread, thanks to the ice/dragon's ability to counter greninja, so I think it makes sense for that set to be A- here.
Magnet Rise Air Balloon Magnezone: This set is very niche, but when it works, it pays off severely. It's able to check excadrill, use magnet rise, and then proceed to only have 2 weaknesses. If you remove all strong neutral attackers + fire/fighting types, this set will pay off dramatically. It requires extreme team support though, so I think C+ makes the most sense.
Choice Specs Magnezone: When I use magnezone, I'm looking for a) a steel trapper and b) a birdspam check. Specs Magnezone can't do the latter, doesn't help dramatically with the former, and doesn't help in any additional niches, so I really don't see any reason for it to be ranked as high as Raikou. I honestly think it deserves C rank, the same rank Zone had before it became popular in around August, since it really does nothing amazing.
Rain Dance Tail Glow Manaphy: Just specify that this is RDTG manaphy and not tg manaphy, since TG + 3 attacks isn't deserving of a rank imho.
Specially Defensive Skarmory: None of the threats it walls are special - it's nearly always better to go physically defensive and handle everything it's supposed to handle better. Mega Gardevoir 2hkos after sr, and that's the only mon I'd really consider this for. Tbh I'd unrank it or make it D, since it's probably as viable as Dugtrio.
SubPuP Victini: Victini has three wallbreaker sets, so I think it's important to draw this line. SubPuP is really good because it's able to, behind a sub, get to +1 on slowbro and +2 on heatran, and subsequently beat both. I think this set is worthy of B+, for its ability to trash common checks/counters without sacrificing much (uturn/brick break aren't missed that much).
Choice Band Victini: Extremely powerful at the start - it doesn't need any set up. However, because it can't setup and can't switch its moves, it isn't getting past its defined counters/checks ever, so I think B is fitting.
Special Victini: This set lacks the power + reliability of the other sets, due to its moves' poor accuracy, so its immediately less viable. However, it is able to lure in and ko physically defensive mons, so I think B- is fitting.
Choice Band Kingdra: If you aren't using Draco Metero + Hydro Pump on Kingdra, you're using it wrong. This set should be removed imho.
Choice Specs Kingdra: This set, however, is really good, and the damage increase is often worth the inability to switch moves. I'd say it belongs in B, along with the mixed attacker.
Life Orb Omastar: Omastar needs Choice Specs to do things like 2hkoing eviolite-less chansey and ferrothorn. Sure, life orb allows it to switch moves, but it also wears it down such that it can't check talonflame well enough, and it also stops it from 2hkoing everything in its capacity, so I personally don't think it should be ranked.
Bulky SD Scizor: Works as a replacement to Mega Scizor on teams that already have a mega. B is fine, since it's pretty much as viable as CB.
Life Orb Staraptor: Staraptor rarely will use a move other than Brave Bird, and if it does, it's going to want it to be as powerful as possible. LO is never really worth it on Raptor, and I don't think it should be ranked.
Agility Mega Ampharos: Requires extensive team support to be good + needs mega slot. C+ rank is more fitting for it imho.
All-Out Attacker Mega Ampharos: If Ampharos isn't using a RestTalk set or an agility set, it's a waste. 4 attacks isn't really viable on Ampharos.
Defensive Mega Ampharos: This is a better name for the RestTalk set, since it tends to run physical defense > special defense now, in order to better handle Keldeo. This set checks flyspam, electrics, waters, and fires with its massive bulk + is able to dish out massive damage with its uninvested special attack. This is its best set, and the set that belongs in B-.
SR Explosion Azelf:
SR Rain Dance Azelf:All three Azelf lead sets function basically the same way; all that changes is what Azelf is setting. It provides team support that really nothing else can provide as well, and I think B- is warranted for all of its sets.
Defensive Togekiss: This set is relatively outclassed. Unless you specifically need your clerical fairy type to have defog / be a flying type, Clefable is much better alternative. That doesn't go to say that defensive toge is useless though, since it does handle chomp/lando/keldeo better. C or C+ makes the most sense. It is a defogger that ohkos bisharp, so I'm thinking c+ is fitting for that niche.
Baton Pass Togekiss: This set uses toge's nice defensive typing to switch in on common threats, boost its special attack, and baton pass to a more threatening special attacker, like Greninja or Agility Ampharos. Its ability to provide support is equal to azelf's, and therefore i find this set fits in B- perfectly.
Offensive Togekiss: This set abuses Togekiss' great two move coverage (Flying/Fighting) and Nasty plot in order to sweep weakened defensive teams. It's able to beat Ttar and Heatran, two mons that otherwise would give it trouble, as well as check bisharp, something no other fairy can do effectively. Its poor speed keeps it from pummeling offense, but its resistances to dark/fighting/ground/bug/grass allow for some switch ins. B- is fitting for this set.
Choice Specs Magneton: This set has absolutely nothing over Choice Specs Magnezone (the extra speed doesn't matter if you're not running a scarf, or even max speed), so it certainly shouldn't be ranked.
Dual Screens Bronzong: Not its main niche, better done by Azelf, etc etc etc. Probably shouldn't be ranked, but D is ok.
Defensive Bronzong: This set handles chomp/lando/landog/gardevoir/drill really well, and is able to fit on most teams using defensive Jirachi that find themselves ground weak.
Dual Screens Espeon: Pretty much 100% outclassed by Azelf. Not worth ranking.
CM Espeon: This is its main niche, and it is used on BP teams to success. I think C is fine for this set.
Focus Sash Lead Infernape: Really solid lead able to cripple other leads well. I think C+ is fitting for this set.
MixApe Infernape: It can't beat offense, but performs superbly against defense. I'm not sure of where in the C+ to D rank it belongs, but it should be ranked.
Choice Scarf Rotom-H: Choice Scarf is pretty bad on something that's so easy to switch in on by megas. I wouldn't rank it, mainly because of...
Defensive Rotom-H: This set makes use of Rotom-H's unique defensive typing in order to wall bird spam/chary, instead of simply trying to outspeed it. I think this is the set that makes Rotom-H worth C.
Defensive Seismitoad: This set is in part why Seismitoad rose from D to C. Take Gastrodon and replace reliable recovery with stealth rock, and you have defensive Seismitoad. It's able to pivot on water moves, and performs specifically well v. rain teams. It also is a great electric-type switch in, and can knock off opponents' items. This set deserves C, along with the rain set.
Offensive QD Volcarona: Able to beat Heatran, unlike defensive QD sets. It's over 1.5 times as strong, so it's able to beat things that resist its moves, like Latios, after they take a tiny bit of prior damage, and that niche imo puts it on the same level as defensive volc.
Assault Vest Heracross: This is just the set it's ranked for, so it should be listed.
Assault Vest Metagross: It only ever runs Assault Vest, so I think that name is better than Pivot.
Scarf Salamence: Only runs Choice Scarf, so that name is more accurate than MoxieMence.
