I decided on a more minimalist VR this year. I'm known to build pretty conservatively; for the most part, these are Pokemon that I'd probably actually use. More broadly, this list roughly summarizes the Pokemon that I "respect" in the builder. I consciously consider answering them when I build teams, even if I don't use them myself, and I don't take for granted that I can probably just outplay them with any random set of Pokemon. I don't think I'll talk about everyone, just those that I think have experienced shifts in the metagame or may have interesting placements. Or I might just have something I want to say.

Charizard is the best Pokemon in RBY NU. It appeared on every team I used and every team I built. It's a solid lead and the single best win condition in probably any RBY tier. Even more so than Tauros, if there is a Charizard, there is a way. Players who use Charizard well are virtually never out of contention to win a game until their last Pokemon faints. Think players like Toxin Boost who know how and when to press Charizard entries and convert them not into "progress," but into outright victories. Players who don't
constantly respect Charizard will lose a lot of games they shouldn't. Simple as that.

Mr. Mime is still really good and everyone knows it. However, this has to be the most misused Pokemon in any RBY tier. I've said this so many times before in the Discord and I am going to publish it here now: you do
not need to click Thunder Wave to start every matchup, particularly in the Mr. Mime ditto. I have won so many games by just attacking the opposing Mr. Mime with Seismic Toss instead of clicking Thunder Wave. While clicking Thunder Wave is a very justifiable play, potentially even in a majority of situations, it should distinctly not be your default play. Let's assess some considerations.
Mr. Mime isn't nearly as much of a win condition as people like to pretend it is. It isn't fast enough, enduring enough, or strong enough to muscle through multiple Pokemon in most games. This is just a reality. Mr. Mime will usually want to trade, often with itself, and that's okay. Cutting to the chase with Seismic Toss, especially if you catch a switch, is just better if we look strictly at the one-versus-one, which actually kind of matters for this Pokemon in this metagame.
Moreover, damage is king in this metagame. When we look at most of the Pokemon that usually win games in this tier — Charizard, Seadra, Fearow, Moltres — notice that they all either can or do outspeed Mr. Mime. These Pokemon need damage on Mr. Mime to sweep through it, not paralysis. Mr. Mime is very frail. A Seismic Toss or two will allow win conditions to muscle through Mr. Mime with no need for paralysis. To make it a statement: if most or all of your remaining Pokemon, especially the one you plan to win the game with, are faster or can feasibly become faster than Mr. Mime, do not bother with Thunder Wave. I saw at least a few RBYPL VI games where a player clicked Thunder Wave in a Mr. Mime ditto when all they had left was like Charizard and Fearow. These Pokemon don't need paralysis to win. They need damage.
There is no ubiquitous rule for this. If you think you're winning the game with something like Porygon, Nidoking, Golduck, or a Swords Dance user that isn't Charizard, then by all means, click Thunder Wave. That's probably your best move. But please actually think about what you and your opponent have left on your teams before thoughtlessly clicking this move.
Additionally, there is this prevailing school of thought to avoid the Mr. Mime trade at all costs. Players get oddly spiritual about this exchange, like it's the dividing line between old and new players or bad and good players. Avoiding the Mr. Mime trade is, to put it bluntly, just not that relevant in the outcome of the match, and whether preserving your Mr. Mime for the lategame matters will fluctuate wildly on a game-to-game basis. Again, Mr. Mime is seldom a sweeper. It is largely most useful for trading, so if it trades for Mr. Mime and maybe a sacrifice later, so be it. That's a job well done.

Some people refuse to put Venomoth in S because it's not a true 100% usage Pokemon like Mr. Mime and kind of Charizard, but wow is it so much better than everything else below it. People act like this Pokemon is a necessary evil that is good because of Sleep Powder and Stun Spore and not much else. This is so wrong. Venomoth boasts an excellent defensive typing (a lot of Pokemon struggle to hit this for super effective damage), a great speed tier for revenge killing and maintaining pressure, and a Psychic that is incredibly difficult to contest. A lot of people forget that Venomoth is actually a real Pokemon and make teams that get absolutely destroyed by it. Think before you sleep sack this, it's not an OU Jynx.

I hadn't been a huge fan of Kabutops historically, but it felt really good in the current meta. Fearow and Moltres remain really common and Kabutops can often secure these matchups comfortably. A good speed tier and decent typing allow it to be pretty useful even if it doesn't find a Pokemon to counter. I was shocked by how much I used it, but my opponents kept running teams weak to it.
One thing that is quite notable about Kabutops is that it really can't be walled (Gastly is probably the closest you will get). I find that a lot of players will build themselves into a corner by bringing too many Pokemon that have one or more difficult matchups. Contrary to what some may believe, I do think NU has many options for sturdy builds that are at least passable into virtually every matchup. You don't really feel like you're setting yourself up to fail against anything when you run Kabutops, or any of the Pokemon above it on this VR. The fact that you secure matchups against two tough Pokemon is really more of a bonus than the key selling point for running Kabutops. I do think a handful of the Pokemon coming up next on this VR can be a lot more impactful than Kabutops, perhaps even if we consider average performance, but the low points of these Pokemon are often what caused them to be placed where they are.

Seadra is still my GOAT. I'd probably call it the second-best win condition in the tier (Charizard takes it for me, and I'd maybe argue that the next contender, Fearow, usually makes for a better breaker than a sweeper). It beats anyone who slacks on Water-type Pokemon comfortably and can circumvent tough matchups if you don't make its presence on your team too obvious.
By the way, Water Spam is an incredible archetype. I've seen the RBY Discord call this fishy and bad, but it is incredibly solid. There are no win conditions that can chain kill Water-type Pokemon, so they simply are not a liability. Yes, Mr. Mime and Magneton exist, but they cannot sweep through Waters. Mr. Mime is frail and likely to get drawn out early anyway. Magneton is slower than every Water-type Pokemon except Poliwrath, which it merely ties, and most of them (especially Blastoise) can and should tech Earthquake to deal like 50%. I think every team I built had at least one Water-type Pokemon, with teams of two or even three being in my builder as well (especially if one is going to be leading).

I have long maintained that Porygon is an NU Pokemon, and it now feels better than ever. A lot of Pokemon are just plainly incapable of making permanent progress against this Pokemon, because Porygon is virtually the only Pokemon in NU capable of reversing progress (using Rest is kind of hard and Staryu isn't really viable). In NU, there is absolutely nothing worse than allowing your opponent to make permanent progress while you make reversible progress. Most Pokemon cannot afford to mess around with Porygon. If your Pokemon can't make progress, you probably need to get it out, because Porygon is actively restoring itself while you sit there, mulling around for a critical hit or whatever. I like to run things like Amnesia Golduck and Swords Dance Kabutops from time to time just because they are Water-type Pokemon that can get around Porygon in a pinch without counting on something else paralyzing it first. Porygon can and has beaten entire teams alone and it has a number of sets with which to ruin your day. This is a real NU Pokemon that you need to respect and should probably run.

I unironically think we could look into banning Poliwhirl. It does not play the game. I don't like using Poliwhirl very much because it's really not that sturdy in a tier that has a lot of really strong options that can assemble a decent backbone. Poliwhirl can get in the way of this consistency. However, when you do not have the time or bandwidth to actually play NU, you can just use this Pokemon instead. Hence my Week 6 set.
While it should basically always be a lead, Poliwhirl has a decent Speed tier, so it happens to have a passable late game prowess as well, if you can keep damage off of it.

Typically, a different Water-type Pokemon will be preferred to Golduck on your team, but its access to Amnesia and a Speed tier above that of Kabutops make it worth considering on some teams that really benefit from one or both of those traits. Using Poliwrath, Blastoise, or Golduck (or some combination) should be a calculated decision based on your team's needs. All are pretty solid. Poliwrath narrowly takes it for me because of the utility of Hypnosis, and the surprise option of Amnesia. Thanks to typing and stats, Blastoise is a slightly better defensive piece, giving it a strong case to be used over or alongside Poliwrath. It's one of the best backbone Pokemon in the tier (contrary to what I've seen some people say recently). Golduck's bulk, while comparable, is consequentially worse (see Charizard calcs, for example), and it sadly does matter pretty often. But the downsides aren't always felt and the upsides are nice. It seems a bit excessive to have three pretty similar Pokemon all in NU (and a whopping six Water-type Pokemon total), but I do think all of them sufficiently justify their existence at this point.

Raticate just honestly isn't that great. I wouldn't call it bad or not NU by any means, but its damage output really just doesn't justify its pitiful bulk and good but not great Speed tier. I used this Pokemon a few times on instruction from my managers, but it never really felt solid. Even though Raticate is much harder to truly counter, Fearow always felt better thanks to a superior Speed tier, immunity to Earthquake, and passable bulk.

I've never been a huge fan of Nidoking in NU (and I think it's terrible in UU), but it has a place. I saw a lot of Magneton this tournament and I think Nidoking has the lowest opportunity cost of all the Pokemon that hard counter it. It's the only Ground-type Pokemon with a real Speed tier, so it can at least revenge kill or something if it doesn't find a great matchup. It's kind of like Kabutops in that regard, but Kabutops has a higher floor on its performance. Can't believe I used this Pokemon, and multiple times at that.

Magneton is kind of bait. While it has incredible damage output and multiple strong matchups into high-profile Pokemon, it is simply incapable of converting good matchups into sure wins. Magneton is slow and fairly frail. The Pokemon that it beats in a head-to-head are very capable of overwhelming it over the course of a match. Unlike say Seadra, it can't dominate a strong matchup simply because it lacks the tools to sustain a sweep. That's it.
Magneton has its uses and probably ought to remain NU, but it isn't something you should use particularly frequently. I used it a bit to start, but then I played Magneton + Fearow into a Graveler and felt completely helpless, which is largely an avoidable feeling in NU. Remembering that I can just run a solid build, I nearly stopped running this thing entirely because there is little point to fishing with it when it can't even dominate its good matchups. Meanwhile, its bad matchups are some of the worst matchups that you can reasonably construct in NU. Compare this to something like Nidoking, which is strong in its good matchups and just kind of mediocre to below average in its bad matchups.

I think Graveler is a very real Pokemon and I do respect it when I build teams. However, I never like building with it. I suspect it might just be my playstyle or team preferences, but I find Graveler to be a regular liability. It can be very difficult to position with a horrific speed tier and two 4× super effective weaknesses. I know other players can get it to work though, so it has its place.

Arcanine isn't great. It has decent bulk and Leer has been a very cute development for it. It also contests Mr. Mime, Venomoth, and Moltres pretty well (though beware of Rest on Moltres). However, I think we are in a very Water- and Porygon-heavy metagame right now, so Arcanine is looking especially unemployed. Ever since lead Mr. Mime started fading — and it should, lead Mr. Mime is bad — I personally stopped really running it, but nowadays, I
really don't see much utility.

Venusaur just does not fit well in this metagame. It invites in numerous dangerous Pokemon, including Charizard, Mr. Mime, Venomoth, Fearow, Porygon, and Moltres, to which you really should not be giving free turns. Its decent into Water-type Pokemon, but it's not really a counter to Water Spam or anything, given how much damage Blizzard does and how easy it is to find a Pokemon that can switch into Venusaur on most teams. The main thing I ever want to use Venusaur for is to get a sleep inducer that can comfortably contest Magneton.

I saw Sandslash get used a few times, but I really don't know what it's doing. It has good damage output, but the Speed tier leaves it in a worse position than Nidoking in most cases. It'd probably be next on the VR if I was being exhaustive. I really don't have the data or experience to sincerely want to rank this.

I considered Rapidash a few times, but never used it. I think the Speed tier could be worth it. It's not terribly uncommon for Charizard and Fearow to sit around in the late game with just a a little health. Aside from Aerodactyl and Scyther, Rapidash is the only Pokemon that can capitalize on this without needing Agility. Like with Arcanine though, I just don't think it's particularly compatible with the current metagame.

Exeggcute is so bad. Do not use it. It is not viable. I will not rank it.
Exeggcute loses to basically every single Pokemon in the tier, and badly. Mr. Mime is its only decent matchup, and it's honestly not even that great beyond clicking Explosion. "Trading Exeggcute for Mr. Mime to free up your own Mr. Mime" is not a credible strategy. As stated all the way at the beginning of this analysis, Mr. Mime is not sweeping in the majority of games. You are trading with a Pokemon to free up a different Pokemon to go trade. That is your best case. Exeggcute has very few reliable entry points because it is slow and can be OHKOed by almost every Pokemon (factoring in critical hits), so it might do nothing. Every time you think Exeggcute could be a good addition to your team, strongly consider using Venomoth instead.
Did you know Magneton beats this one-versus-one? Magenton can even win upon switching in.
