Bug
Alongside being a Fire immunity, Centiskorch is also the best Steel breaker with its Fire STAB in combination with Scorching Sands. With Steel being prominent right now, Centiskorch rising should reflect on it.
Dark
Dark prefers balance in order to use more Pokemon to tech for more matchups and would rather not dedicate a teamslot to Stealth Rock when Tyranitar is already a great setter.
We felt it was appropiate to rise these three Pokemon as they all do well against good types in the metagame which would otherwise be hard and are good alternating options for an unfilled slot on Dark teams. Weavile does well against Dragon, Ground, and Flying, Drapion breaks Fairy and Electric with Toxic Spikes, and Zarude makes the Water matchup doable while also helping against Ground.
Don't use Obstagoon over better breakers.
Dragon
Latias is so much better than Latios as a Choice Scarf user now to the buffed Healing Wish, so Latios drops.
Hydreigon is great on Dragon teams, being able to serve as a Ghost resist for Spectrier, while beating other types like Ground and Steel with its power.
With Kyurem-B gone, base Kyurem again rises in popularity. Both Choice Specs and SubRoost sets are very dangerous to many types across the board, with Choice Specs being obscenely strong and SubRoost PP stalling a number of foes.
Zygarde-10% has fallen off as it lacks breaking power to consistently break through the types Thousand Arrows would otherwise capitalizes on. It has become a rare sight on Dragon teams because of this.
Noivern is hard to justify using as a Defogger when Latias is so great; although Taunt and U-turn keeps it ranked.
Offensive Regidrago is a meme at best and doesn't cover anything in particular which others can't cover. Screens Regidrago is outclassed by Duraludon by virtue of typing. Regidrago has no niche, so it is being unranked.
Fairy
Tapu Koko is now a more flexible slot on Fairy teams and struggles due to overlap. Pokemon like Alolan Ninetales, Tapu Lele, Clefable, and Tapu Bulu covers the matchups it primarily capitalizes on well in Water and Flying.
Clefable is really nice for role compression. Knock Off + Rocky Helmet is nice for weakening Celesteela and other bulky Pokemon and removing Heavy Duty Boots which makes it splashable as a Stealth Rock setter. Calm Mind can also be dangerous when paired with Klefki's support depending on the set you choose to run.
Alolan Ninetales is a good option on Fairy teams to tech against weather types like Ground, Water, Fire, and others like Flying and Dragon with its combination of Snow Warning and Ice-type STAB in Freeze Dry and Blizzard.
These four Pokemon have fallen out of fashion on Fairy teams and have dropped a rank in reflection of this.
Fighting
Conkeldurr has a hard time fitting onto teams.
Toxicroak is nice for Water, especially now that Tapu Fini is prominent.
Bewear is unneeded on Fighting so it's now unranked.
There's no reason to use this over Urshifu-S and Keldeo.
Fire
This is a worse Arcanine; Arcanine has better coverage and Intimidate alongside priority in ExtreemeSpeed.
Flying
Mantine and Mandibuzz are everywhere on Flying teams now as they both have great defensive typing and bulk to check many key threats across the board. Mandibuzz primarily rose in usage due to check the ever so dangerous Spectrier, but its bulk also lets it stomach hits from Pokemon like Zygarde-10%, Nidoking, and Excadrill, and has a decent set of utility options at its disposal. Mantine is great for checking Water with Urshifu-R and Dracovish, as well as Fire with its typing and Water Absorb.
Thundurus-Therian is really splashable on Flying, breaking apart teams with Nasty Plot or being an incredible pivot with Choice Scarf Volt Switch. It's also an Electric immunity, which provides it utility in the form of being able to come in on Pokemon like Tapu Koko and check SubToxic Zapdos.
Ghost
Spectrier is an extremely centralizing threat as of right now that many types across the board should keep in mind when teambuilding. Types like Poison, Water, Flying, Steel, Dragon, Psychic, Ground, Fairy, and Grass, all have the potential to be swept by a well played Spectrier, and it's by far one of the most dangerous Pokemon on the type.
Galarian Corsola is excellent glue for an offensive type and Ghost teams lose to so much without it. It also sets Stealth Rock and burns things for Spectrier to come in and sweep.
Ghost is an offensive type and Jellicent has fallen off when the type relies on offensive Pokemon to break things like Water and Fire.
Chandelure is a worse Blacephalon, while Dragapult's Infiltrator means it is also useless in that department.
Grass
Cradily can carry Stealth Rock so Ferrothorn can use Spikes and has Toxic for reduced passivity, which puts it above Appletun as a Fire check. Grass teams rely on offensive pressure fine to check the Pokemon Cradily cannot like Victini and Celesteela anyways.
Sun Grass has fallen off a lot, especially when Steel teams now have Heatran to play around Weather Ball spam, so Venusaur falls with it.
Sceptile is too weak to be threatening as a sweeper.
Ground
With Landorus's ban, Nidoking has taken its place as a Special Attacker.
Landorus-Therian is more splashable now that there is no opportunity cost of not being able to use Landorus.
Rhyperior has no niche now that Nidoking exists as a Corviknight check.
Ice
Galarian Darmanitan rises to S now that the bar is lower with Kyurem-B being gone.
It's not unusable for certain Perish trap sets and Choice Specs. It's a nice Water immunity as well for Dracovish.
There is no oppurtunity cost of not being able to use Kyurem-B, so Kyurem resumes its role as a great Special breaker on Ice teams.
Poison
Galarian Slowking has risen in popularity thanks to its good defensive typing in combination with Regenerator and high special bulk. With Assault Vest, it's a solid switchin to many Special Attackers across the board which would otherwise tear through Poison like Kyurem, Alolan Raichu, Tapu Lele, Alakazam, the list goes on and on. It helps turn matchups like Dragon and Electric from borderline undoable to an advantage for Poison teams because of this, and adds onto the defensive core to make it extremely hard to get past.
Nihilego is the flexible slot on Poison teams that is being dropped if you'd like to fit something else like Salazzle, Galarian Slowking, or Gengar. It did not get worse, it just isn't on par with the rest of the A ranked Pokemon which are basically defined slots on Poison due to the type's rigid team structure.
[20:36:25] #Decem: bat is sooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo baaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaad
There's no reason to use Vileplume when Amoonguss's Regenerator is so much better for longevity. It also lacks a correct way to check Swords Dance Excadrill.
Salazzle is super hard to fit on Poison teams nowadays in place of other options, namely Nidoking.
Skuntank is in an awkward spot on Poison. With its main niches being Defog to remove hazards and Sucker Punch to check Alolan Raichu, it struggles to find a spot on teams with teammates like Galarian Weezing and Galarian Slowking. Galarian Weezing Defogs, and Galarian Slowking serves as a very nice check to Alolan Raichu.
Drapion takes the place of Skuntank as a Psychic immunity now that it's less mandatory. It's better otherwise with moves like Toxic Spikes and Knock Off.
Assault Vest Galarian Slowking being great means Assault Vest Galarian Slowbro drops.
Rock
Ground is good right now so the Ground cteam on Rock rises.
Steel
Celesteela faces more competition with Skarmory as seen in MWP recently, as Skarmory is a much consistent answer to the Urshifu forms with its reliable recovery in Roost while being able to set hazards. Celesteela is still good, but dropping to A reflects this slight drop off in viablity.
There's no reason to use Metagross over other offensive options on Steel, namely Jirachi which is a great Special breaker and takes advantage of Psychic STAB much better.
Water
Tapu Fini has a variety of good utility assets that make it a great option on Water teams. A Fairy typing along with Fairy STAB is really nice for checking Dragon teams, while providing a sturdy Dark resist for Urshifu. Misty Surge is also useful for protecting the Water team from being burnt by Hex Spectrier. Between Calm Mind + Taunt, Choice Scarf, and Defog sets, Tapu Fini is an incredibly splashable Pokemon on Water teams which rising to A reflects.
Seismitoad frankly sucks; Swampert is better in it even on Rain due to Flip Turn generating momentum for more consistent threats like Urshifu-R, Kingdra, and Barraskewda to break. Swampert also gets Roar, preventing Pokemon like Dragon Dance Dragapult, Dragonite, and Substitute Kyurem from doing too much damage to Rain teams by forcing them out.
Cloyster is hard to use as a Dragon answer now that Dragonite gets ExtreemeSpeed to pick it off. It can still run Shell Smash to a less consistent degree and certain Choice Scarf lure sets, but it took a huge hit in viability once DLC 2 dropped. Running something like Tapu Fini or Kingdra is more ideal to get an upper hand against Dragon teams now.
Volcanion is hard to fit, so it drops.
