There hasn't been much discussion so now that the previous season is over, I'll take the time to at least post a few other noms that will be voted on. These were all brought up in discussion during our previous vote but weren't voted on at the time. Umbreon was one of them but this was just nominated so I won't go over it again.
These are not official changes, just nominations that will be voted on next council vote.
Latias: UR -> B-/B
Similar to Latios, it sits at a solid Speed tier trading a bit of power for bulk, allowing it to function as a better CM user than Latios. Access to Healing Wish also gives it a very nice last-resort option to heal a teammate similar to Lunar Dance Cresselia. It shares all of the same problem as Latios though, namely that its STAB combination isn't great and 110 Speed tier isn't
quite as good as it used to be. It's also a Psychic-type that can't abuse Psychic Terrain without resorting to weird stuff like Gravity support, so it misses out on one of the best new tools for its type. It's an excellent Blaziken teammate though and greatly benefits from its rise in usage thanks to Blazikenite's release.
Espeon UR -> B-
Espeon still holds the title for best Baton Pass recipient on dedicated BP setups. While not much has changed for it, Espeon still remains about as effective as it was in ORAS. It can also function as an effective Dual Screens setter thanks to Yawn though it does face some competition in that role from Alolan Ninetales. It usually struggles to fit on teams otherwise but it's definitely worthy of a rank.
Golisopod UR -> C
This is an unusual choice that I initially didn't want to include unless
Jhon or
Theorymon posted it, but after having run into it on a decently high rated team I'm willing to give it a chance at being ranked, especially since it gets similar usage to some Pokemon we have ranked already. While it hates Lele's presence and its ability is a double-edged sword, Golisopod actually boasts a great typing and bulk that lets it check pivot into physical attackers like Mamoswine and Garchomp. It has great Attack and a decent STAB combination that lets it function as a decent pivot with Choice Band or Sitrus Berry, and while its ability can easily force it off the field when it really doesn't want to, this can be played to the Golisopod user's advantage due to its priority options.
Blaziken A+ -> S
This is something that came up a lot in discussion on whether or not to move Mega Blaziken to S, but a prevailing thought was that the unpredictability that Z-Move Blaziken and LO Blaziken provide also contributes to how scary Mega Blaziken is, and that both should be ranked in S. Mega Blaziken's superior Speed tier and consistent power definitely make it worthy of S regardless, but Blaziken's other sets shouldn't be taken lightly either. 80 is not a great Speed tier to be in, but Blaziken as a whole is just an insane Pokemon this gen.
A few other proposed changes of my own that I'd like to vote on are Buzzwole, Snorlax, and Eevee.
Buzzwole B+ -> B
Buzzwole is still a very usable Fighting-type especially between Beast Boost and its amazing physical bulk, but it faces a lot of competition from Mega Heracross who is typically the better choices even though it takes a Mega slot. Buzzwole still boasts access to Thunder Punch and Ice Punch, as well as reliable recovery that make it a fantastic physical tank and decent Choice Scarf user, but I think B+ is too high for this.
Snorlax UR -> B
Snorlax is a really cool mon in BSS and surprisingly versatile between Curse sets and Yawn + Whirlwind sets. It faces competition from Mega Kangakshan as an offensive Normal and from Hippowdon as a phaser, both of which usually fill those roles better, but pinch Berries + Recycle give it a lot of longevity and it actually makes a good special sponge alongside Hippowdon itself to augment its phasing potential. Blaziken being everywhere does it no favors but if you don't have a Fighting-type or Toxic user, Snorlax can quickly become a huge pain to beat.
Eevee UR -> C
We thought Eevee would die post-bank, and it kinda did for awhile, but EeveePass is still very viable even though Blaziken existing makes life even harder for it. EeveePass still has matchup nonsense that can make it very powerful against teams that lack good answers to it, but it absolutely needs solid team support to function and it struggles against a lot of stuff post-bank.
Feel free to nominate any other changes though, there's still time to get more nominations in before the next council vote, this is mostly a reminder since the season just ended and there are definitely meta changes worth discussing that aren't reflected on the VR yet.
