new VR (deleting old one)
Explanations:
S (best of the best, should be on most good teams):

I can admit that Dug should be #1, but the way Articuno guarantees sweeps through teams has to have me putting it at #1. Clearly, people are not playing optimally around it, but it has no true walls, and can be used in the early or midgame to open up other teammates. Lead Cuno is one of the sets that I think should be explored more, with all out offense backing it up.

The ultimate bullshit mon, can easily crit through whole teams especially how often teams stack mons that get crit OHKOd by this. Also the best revenge killer in the tier, can easily Sub up on sacs, etc etc. Has the strongest case for #1, but lately many players have been stacking Dugtrio checks, and while it can still get much work done, bringing multiple checks and not much Haunter really limits it.

One of the most splashable mons, to the point of being near undroppable IMO. Its switching into Tentacruel freely coupled with how it is one of the few mons that can switch into it's own Psychic. However, letting in physical attackers for free on its recovers, and Dug on its TWaves, really hurts it as a mon.
S-:

This is still clearly one of the best mons in the tier, being the only real defensive Cuno check who outspeeds, and being able to choke out half the tier is amazing. However, I often struggle to fit it on teams due to how it doesn't actually hard check anything. Dewgong is a better Cuno check, it struggles to check opposing waters due to their good physical bulk and resistance to Surf/Blizzard, and nearly every team is bringing many different ways to check it. At the end of the day though, the more dynamic lines and other upsides mean I can't rank this any lower than 4th.
A+ (Great mons, should be heavily used):

Great mon, can pull off reverse sweeps like nothing, and STAB normal moves off that attack sting af. Being the best Dug EQ switchin and the only one that's actually a good mon outside of the Dug matchup is massive, but being OHKOd by Cuno/Gong is also really bad for it, as well as the rise of Golem. At the end of the day, it's still a great mon as nothing can switch in apart from Cuno, Golem, and Omastar.

Honestly I debated putting this over Dodrio, as they're extremely close in my eyes, as Normal-type attackers that also serve as counterpunching Dugtrio checks. Flipped them this time, the bullshit level of Dodo is too good. Leading Kang is a nice new innovation and it's still the same mon as it's always been.
A:

Great mon, second best Cuno check while bringing great offensive potential with BSlam for Tent and Kad. Soft Dug check, and spamming it really deters opposing Cuno too. Not much to comment on honestly.

Best sleeper in the tier by a long shot, Explosion lets it serve as a solid Cuno check, but really feels like it's worse than the other top mons. Being OHKOd by Dug EQ is awful for it, but the Tent and Kadabra matchups are surprisingly playable (Explosion OHKOs Kad, mutual 3HKO with tent but Psychic special drop chance), and its mere existence in the tier forces Kangs to think twice before clicking Normal moves. Missing Hypnosis into getting crit combo is never nice tho

IMO the best and most solid (I guess least bad) all around lead in the tier, matches up fine vs pretty much every mon. Main issue is Golem who is a capital T Threat, but has all around solid matchups across the board vs other top mons
B+ (Have these mons in your usage stats):

Idg why everyone keeps underrating this mon. Pressure from Haunter/Golem forcing Kang to click EQ gets this mon free entry points, and it has the coverage and stats to farm the entire meta. Hydro Pump accuracy is the main issue for it, while you can use Surf it misses out on the Kang 2HKO. Fire Blast is also a new cook, leaving the best non-Haunter check in shambles and games Kang too. Great Dugtrio check, is fine switching into Kadabra, great.

The best Dodo answer, has no switchins (base 110 attack with STABs hits like a truck, who would've guessed). Most teams without Tangela have to resort to trading for it with Kangaskhan/Clefable or pivoting out of their mind, or just accept that it'll go 1.5-2 for 1. Rock Slide essentially has no switchins, apart from opposing Golem who gets cooked by EQ.

This mon feels like an alternate Gyarados, with Wrap and Twave instead of stab to threaten Kang/Haunter. Pivoting is always nice as is the Hyper Beam/PT bug, but Gyara feels like it has a better matchup spread. It in the lead slot, with or without Agility, is also pretty nice.

Great lead which nothing wants to switch in to, that special combined with STAB FBlast is great, Dodrio/Tent speed tie is also great, might honestly be the best lead. I doubt it'll be ranked UU on the final VR but it deserves it for sure.

Great mon. Feels like an alternative Dragonite, can tech many different moves, such as Tbolt for Dewgong, Counter for Kang, Sing for free sleep, etc etc. The 4MSS is there but it doesn't really NEED any of these moves, BSlam Blizz HBeam works fine, and its bulk lets it often 1v1 Tentacruel.
B

I know I was very low on this at the beginning of the meta, but it's really proven itself to me despite my 0 usages of it. Best Dug wall in the tier, eats hits from pretty much every mon without SE hits for it. After Sleep it's not threatening at all and most sets being "walled" by Golem is pretty funny, but you can't say no to a Dug wall packing an OHKO button.

Not a great mon and destroyed by Haunter, but it'll farm you if you take it for granted. Gyara > DNite is great for it, surprisingly not as awful as thought vs Cuno, revenges a lot of stuff.

Fastest mon in the tier, Explosion is nice utility, etc, but being hard walled by Golem is a huge negative. It's also the best non-Water type at being a Cuno check (Twave if they agilitied, otherwise just Boom if you're in Blizz range). I just feel like the other higher mons are better at their jobs/have better jobs to do.

Feels like a Golem/Dewgong role compressor, but deals with clear problems. EQ weakness leaves it far more susceptible while resting, but without Rest, after Dodrio comes through you just die to Cuno. Hydro Pump accuracy is also a big issue vs Kang (Hydro is needed to get the 2HKO vs Kang). Being a wall to Dnite and Surfless Gong is pretty nice.

Did you know that in terms of water pokemon, Vaporeon is the best Articuno wall? Acid Armor is a cool option to beat physical attackers and waste Tent's PP in endgames. The massive special bulk also lets it trade weirdly well with Electrics and Kad. However, it's pretty crit prone and in most cases you'd rather have one of the other waters.
[cutoff]
C (Mons that have merit, but are generally worse than other options):

Electric type, matches up very well into Gyara/Golem comps but is otherwise lackluster, being an electric type whos Tent MU is a coinflip is really ass, also unfavored flip vs Dodrio, has 4MSS issues (want Agility, want Surf to bully ground types, want normal type move to pressure Kad). The best set IMO is TBolt Surf HBeam Agil, as Tbolt -> Hbeam kills Kad.

Has solid traits like the second best speed tier outspeeding Dug, HBeam resist, revenging many common low HP mons. On the other hand, it's Aerodactyl.

Agility sweeper with strong attack and STAB Fire Blast, might have a niche over Ninetales as a lead but Ninetales is generally better.

Basically Tangela except with a speed tier, without being solid vs Dug, dying to Kad, but can output similar levels of offensive pressure as Haunter (minus the boom part)

Sleeper with tools like Amnesia, Earthquake, Blizzard and resists Cuno STAB, does stuff kinda.

Strong grass stab, Wrap, Double Powder, surely this does something right?
D (Mons that have a niche but should be avoided)

The RBY mascot, Tentacruel speed tie and 2HKOs with EQ, SD Hbeam is pretty strong

Agility sweeper that can set up on Cuno

Mom: we have Dodrio at home, Dodrio at home:

Base 105 speed can only be so bad

Can trade with Kad to open up your own Kad, but slower than Tent/Kang is pretty bad.
E (Pretty much completely outclassed):

Pretty much all the other sleepers are better than it, can't touch haunter and is farmed by most good mons. Even in lead is generally worse than Venomoth or Victreebel as it has no Stun Spore.

I'm only ranking this becausee it outclasses Golduck, awful mon

Dugtrio and Kad "switchin" on more offensive teams and can stun -> boom to open up mons that need a turn of setup, but requires so many reads for a mediocre reward.
F (Please don't use these):

This mon is literally a worse Arcanine, only benefit over it is the Fire Blast guaranteed 2HKO on Kang/Persian after having set up. Literally just always replace this with Arcanine.

Water type but everything it does is done better by Poliwrath and Vaporeon, even Poliwhirl having sleep makes it better as an Amnesia sweeper without a Psychic weakness.

Worse Victreebel, I don't see anyone trying to use this but ranked it anyways.

Imagine being outclassed by Seaking LMAOOOOO, no attack stat means it can't break Tent

This might be the worst Pokemon with a "niche" in the tier as it just fails to do anything.
