Got some noms for you guys to chew on.
Drops:
A+ --> A
If Tauros was moved down because of the relevance of Steelix and the shifting speed tiers, Archeops should as well. I still believe that Archeops is a step behind Tauros in this meta because of its Rock weakness, Defeatist, and inferior bulk. I've already written a huge fuckin essay on the many intricacies of Archeops, so I'll abstain from making another novel, but you can check out my previous post
here. The biggest difference between Archeops and Tauros right now is Archeops's ability to "reliably" 2HKO Steelix with Focus Blast or Heat Wave, but I'd like to bring to attention the fact that Tauros can 2HKO Steelix with Fire Blast with either a little prior damage or even minimal Special Attack investment. These two remain very similar in their wallbreaking capabilities, but I believe Tauros still has the upper hand.
B --> C+
I know a lot of you guys really like Jumpluff, but I think it's gotten much much worse lately. Firstly, Sceptile almost completely outclasses it as a physical Grass-type, sporting a more relevant Speed tier, an arguably better typing, superior bulk, and two more useful abilities. Jumpluff sports some tools over it, such as U-turn, Memento, and Sleep Powder, but I'd argue if it didn't have those tools it should just go unranked. Additionally, its more useful niche of last meta, being a Flying-type sweeper that beats Rhydon and Lanturn, is much less relevant because of the decline in usage of these two threats.
B --> B-
Originally I wanted to nominate Quagsire for C+ because I felt it was the most useless bulky Water-type we have in the tier. However,
QueenOfLuvdiscs was able to sway me to at least keep it in the B Ranks because of its ability to check some remaining relevant mons, such as Rhydon, Malamar, and Jynx (requires a bit of Special bulk investment). However, it's one of the biggest momentum sucks in the tier and invites in the scariest sweeper/wallbreaker in the tier, Sceptile. It only fits well on very bulky teams which are still pretty subpar.
B --> B-
I know we recently dropped this, but I'd like to see it dropped a bit more. Zangoose is by no means a bad wallbreaker, but I think most players would prefer to use one that doesn't require as much support, preparation, or is as susceptible to whittle. Tauros, Swellow, and Kangaskhan may not have as much explosive power as Zangoose, but what they do have over it is the perk of standalone consistency. All three of them are powerful enough without the need for Pursuit support, slow pivots, or fear of whittling themselves down. Zangoose is far from consistent or splashable nowadays, so I'd be way in favor of dropping it.
B- --> C+/C
Pretty similar to Rhydon in the regard that there's a huge opportunity cost associated with running this mon right now when you consider you can just run Steelix. However, I think the biggest negative associated with Regirock is how passive it is. Essentially any Rock-resistant mon can switch into Regirock fearing, at worst, a Toxic and threaten it out. Hell, Steelix switches into this thing free of charge. I haven't thought of Regirock as especially great since the Typhlosion meta, and it's only gotten worse as time goes on.
B- --> C+
I'm not going to write a big paragraph on this. The most common Rocker in the tier, Steelix, takes a total shit on this thing. HexTom is also one of the most common balance breakers in the tier. Linoone is not very good anymore.
D --> E
I think
soulgazer brought up something like this a while ago, but he doesn't put a lot of effort into his posts anymore, so we might have accidentally ignored it? Long story short, this thing is completely worthless. Any time you could think "hey I should use Simisage" you want to use Sceptile because Simisage is inferior in every way. On top of that, it's not even good because its speed tier is pretty awful for what it wants to do, it's not that strong, and it has pretty lacking coverage outside of Focus Blast.
D --> E
Unranking this was a point of discussion in the previous big update, but I think we decided to keep it because it could still check stuff like Klinklang and Vivillon over Rhydon. Steelix is now the superior Flying- and Steel-type check with a much more relevant niche. I don't know of any relevant Pokemon that Stunfisk beats anymore that you couldn't run something else for.
D --> E
Regular Audino is effectively worthless right now because, if you're running Mega Audino, you have the ability to take advantage of Regenerator before you mega. Passive recovery with Leftovers is kinda cute, but I would never consider it over the ability to transform into a mon with a superior typing and bulk. At least Lickilicky has Oblivious and physically offensive set to maintain some niche, but Leftovers Audino is objectively worse than Audinite Audino.
Rises:
B --> B+
Mismagius is essentially a Rotom with better Speed, Taunt, and no Volt Switch. Stallbreaker Hex Mismagius is a terror for balance teams to cope with right now because of the threat of either status, Will-O-Wisp or Thunder Wave, or just being flat out broken by Taunt. Honestly, though, I can't stress how nice it is to be able to abuse Taunt. HexTom is able to burn stuff and break it down, but never prevent stuff likes Stealth Rock, Spikes, or status. Mismagius does that and beat some stuff HexTom can't, such as Mega Audino. On top of that, it has a variety of offensive options that it can abuse, such as Dazzling Gleam and Thunderbolt. I think Missy is very under-appreciated right now and I'd like to see it get some love.
B --> B+
I think someone else brought this up, but I'll talk it up a little. Barb is one of the few Water-type setup sweepers that doesn't completely hate the presence of Sceptile in our tier. Other Water-types, such as Samurott, Kabutops, and even Ludicolo, can be revenge killed by one variant of Sceptile or another. Barbaracle, on the other hand, has the ability to OHKO every relevant variant of Sceptile at +2. Barb is also able to outspeed every relevant Choice Scarf user without even needing a Jolly nature. Definitely a powerhouse sweeper right now, in my opinion.
C- --> C+
I ran this in OU and it 1v1'd a +1 Special Attack Porygon-Z. I'm serious.
+1 252 SpA Life Orb Porygon-Z Ice Beam vs. 252 HP / 252+ SpD Eviolite Clefairy: 125-147 (36.3 - 42.7%) -- guaranteed 3HKO
+1 252 SpA Life Orb Porygon-Z Tri Attack vs. 252 HP / 252+ SpD Eviolite Clefairy: 165-195 (47.9 - 56.6%) -- 89.5% chance to 2HKO
Jokes aside, though, Clefairy makes a really great check to just about every Special Attacker in the tier and sports some amazing defensive utility with access to stuff like Stealth Rock, Thunder Wave, Healing Wish, and even Calm Mind. Magic Guard means it's one of the few bulky mons in NU that isn't bothered by hazards or status, as well. The fact that I can throw this mon on a team and call it my dedicated Fire resist is a testament to its strength.
252 SpA Choice Specs Pyroar Fire Blast vs. 252 HP / 252+ SpD Eviolite Clefairy: 150-177 (43.6 - 51.4%) -- 6.6% chance to 2HKO
252+ SpA Magmortar Fire Blast vs. 252 HP / 252+ SpD Eviolite Clefairy: 121-144 (35.1 - 41.8%) -- guaranteed 3HKO
I'll make a post later talking about some of the noms that have been brought up. Just wanted to get my own noms out there.
