Okay so this is probably gonna be a pretty big update and a lot of the changes might be pretty drastic. I'm going to crack down more on the rankings of Pokemon to more reflect what the purpose of "viability" is supposed to actually represent. For example, Pidgeot in D is a perfect example of how I want the rankings to look. Pidgeot is a good Pokemon, hits hard, and has a good speed tier. But it's not viable at all in FU because it has no niche. Is it viable in a vaccuum? Of course. Could it do well on a team? Certaintly. But it's so outclassed by other Pokemon found in the tier such as Swanna and Fearow that there is literally no reason to use it on a serious team, thus making it unviable, so ranking it high would ruin the purpose of the thread. Because it isn't a terrible Pokemon and is just really outclassed, it goes in D rank. Anything that is unviable AND sucks will go in E rank; see Unown, Dustox, and Furret. Well, that's enough talking about Pidgeon, I already spoke about it before. Lets move onto the changes!

Changes to A ranks: Because the Pokemon found in the A ranks are supposed to be the most influential and viable Pokemon in the metagame, I will put the most amount of effort trying to accurately update them accordingly in order to keep up with the ever changing metagame. Gabite was moved up because of how splashable it is and how easy it is to fit onto offense/bulky offense, the two best playstyles in FU at the moment. Outside of strong super effective hits it is very difficult to OHKO even pure offensive variants, and with Rough Skin it can heavily discourage people Volt-turn spam which is very common in FU. It may not be able to switch into shit all the time because of its lack of recovery, but it's an amazing check to many top tier threats such as Simisear, which is godly right now, Simicyook before it gets knocked off, Buzz (Evio fails to OHKO with HP Ice), Zweilous, Lairon, Krow, Viper, Klang, and Gigalith. On top of that it's one of the most consistent offensive rockers in the tier besides Lairon. If it was just a little faster or didn't depend so much on Eviolite, it would easily be A+ or even S.
Metang is pretty mediocre at the moment. As a Steel-type there's little reason to use it over Klang or Lairon seeing as how it lacks the raw immediate power of Lairon or the ability to run through weakened teams like Klang. It's also Pursuit bait and takes a shit ton from Knock Off, a VERY common move. With the rise in Zweilous, Duck, Toed, Sear, and Scraggy, Metang just doesn't have nearly as much defensive utility. The two best Dragon-types in the tier, Gabite and Nair, have something to 2HKO it with as well. Dark is just such a commonly used coverage move and most of the tier has something to hit Metang super effectively with. I would honestly drop it to B+ but that's not entirely my call.
Personally I think Gogoat is complete trash in the current meta, and I wouldn't mind seeing it in like the lower B ranks. It's sooo overhyped holy shitttt. It's bulky, yes, and has reliable recovery but outside of that it has basically nothing else going for it that would warrant it a slot over Simicyook, BUCK, or even Servine lol. Simisage has like 2 reliable switch-ins, one of which is niche and has no reliable means of recovery (Swalot) and the other hates being knocked off (Whirl). Buck is basically a frailer, faster, and stronger Gogoat with an amazing dual STAB and Swords Dance. Servine is slow but it completely ass rapes defensive builds and is bulky enough to check shit like Buzz and Toed. Offense wont like switching into a +2 Leaf Storm either, which it can easily get against lots of slower shit. Besides, the reason Goat was so hyped in the first place was because it was like a really solid offensive check to Buzz, but it just straight loses to Toxic variants. The only set I would ever use would involve Sub or Bulk Up, although probably not both at the same time. The meta has just shifted so much out of its favor with the rise in Poisons, Sear, and Sage. It's fucking awful lol, especially now that Buck exists.
Heatmor is another Pokemon that serves little purpose in the meta and there has to be very valid reasoning not to use it over Simisear. Flash Fire is cool and Sucker Punch is cool, in theory. It's main niche in the meta is how it can "check" Simisear, but like, it can't even do that. Without an Ass Vest you're being 2HKOed by practically ever Sear set in existence because every good Sear set runs Focus Blast unless you're tryin to lose to so much shit. It's slow, gets worn down so easily especially with Orb, and Sucker is SOOOO weak seeing how it can't even invest much in physical attack, so the priority is pretty much pointless in most circumstances. I wouldn't mind it in B tbh, but Kush has a boner for it so I guess it can stay B+ for now.
Changes to lower ranks: Most of these are pretty self-explanatory. Ditto is cool and can fuck up HO teams, but it provides little use against bulkier teams and is hard to warrant a slot on teams because it's so matchup reliant. If you know you're facing Kingler123456789 who loves using rain offense or Mambonerfense, use it, but if you're facing Skank stall then u should probably go fuck yourself and use SD Lum Kingler instead. Shelgon is pretty much outclassed offensively by Nair, but its DD set is cool because you can break through Lairon, which Nair struggles against on its DD sets, so B is fine. Dusclops is passive as balls and is only good on T-spikes teams. Again, Scraggy is a god, and Krok, and Zweilous, and Krow. The meta is also prepared for T-spikes now because it's so common. Not too amazing. Magcargo sucks defensively and SS is slow as fuck but it's pretty funny and you can wreck some shit. Can set up on Cate, Krow and shit. Noctowl is really bulky but has like no defensive synergy and hits about as hard as a wet paper bag. If you have bad defensively synergy in FU and no offensive presence, you're gonna have a bad time. Wind Chime is niche as fuck as a Healing Wish user, and I really haven't seen anyone ever use it at all other than blametruth the god. Might be better, but literally have never seen anyone use it and it's literally free food for Krok and Krow. What the fuck is Octillery. It's really annoying with TR support but no one is savage enough to use TR teams unless your name is
Don Honchkrorleone . Glaceon is horrendous, and the only thing that saves it from D rank is 2HKOing everything with Blizzards. Magmar is useless in a Sear meta, Belly Drum is garbage. Lumineon is another Pokemon that has an extremely small niche because it can remove hazards and has like U-turn and shit. Also can Defog on like Golduck or Toed I guess (if you like getting Encored).
Okay so FUCKING BASTIODON. What the hell does this thing even do? It comes in, sets up rocks, prays Sturdy is intact so maybe it can kill something with Metal Burst, than dies. Absolutely zero offensive presence, no reliable recovery, and is practically completely outclassed by Lairon in every shape or form. The ONLY thing that saves it from D rank is how Bastio can check everything Lairon can defensively but 3x as much because of its massive special bulk + Lefties. Other than that, it can't do shit, and I have never been able to use it on a team over Lairon without questioning my sexuality.
Okay I'm done bye.
EDIT: I bumped Furfrou up one rank. It's an alright Pokemon that is less niche than the stuff found in B-. It's not that splashable considering it has like no useful resistances and relies solely on its massive physical bulk to take hits. T-wave is also really nice because you can hard eat up most physical hits and T-wave the following turn. Personally I don't think a full defensive set is what makes Furfrou viable though. Investing fully in Speed in order to take advantage of its trollish 102 Speed tier in order to outspeed the Simis is far too important. Without doing that, Sear just comes in and roasts it with Blast while Sage does a HELL of a lot to it with Leaf Storm. It can also outspeed Cate and CAN take an unboosted Facade if need be and takes barely over 50% from Buck's Silk Scarf D-Edge, that's without ANY investment. It has terrible coverage though and hits like a girl, but Return is still strong, it has U-turn, and can outspeed lots of relevant shit. Being a free switch-in to any relevant Steel-, Rock, or Ghost-type sucks though, which is why it will never go higher than B.
I'm not sure about the other noms Skank, I'll have to look into those more.
