I've been sticking around this tier for a while, saying some of my thoughts abt the vr.

A (2) -> A- (2)
Eternatus is having a worse time right now, with an increase usage of Arceus-Ground, Zacian-C, Hatterene, Calm Mind Tera Poison sets like Arceus-Fairy or Kyogre, heavily limiting its key role of spreading toxic and poisoning others. It also has a bad time facing Miradon, Koraidon and Calyrex-S, which are the top tier mons, as they all threaten Eternatus with their stabs, and which Eternatus can't deal back much damage to them.
(According to the recent AGPL usage stats, Zacian-C has 16.3% usage, Hatterene has 14.13% usage and the both are hard counters to Eternatus)

A- (2) -> B+
NDM has always been losing to top tier threats like Calyrex-S, Miraidon, Arceus-Water, Arceus-Ground, Ting-Lu, and even Arceus with the Bulk Up set. The Trick Room set is often outclassed by Calyrex-Ice, as Ting-Lu also tanks hits from NDM.

B- -> B
Alomomola is a really nice switch in to various psychial threats, like Koraidon, Arceus and Ho-Oh, as well as utilizing Flip Turn with Regenerator, making it a good defensive piviot. With wish, it can also heal up its teamates, like Ting Lu for an example, with a team named axis6 buildt around this core. Alomomola is also very splashable on mostly fat and stall teams, while also sometimes being used on balances.

B- -> C
Dondozo is a great Unawere physical wall, yet sadly having rest as it's only option to heal back itself. However, Miraidon's ability set up Electric Terrain, stopping it to rest unless it terastillizations into the Flying type. The usage of Dondozo has also been rare, as it is often hogging up the tera slot, when stall already has many pokemons that would have more value to rare, like Tera Grass special defensive HO-Oh.

B- -> B
Grimmsnarl is objectively, the best screen setters in the current meta. Screens has always been an amazing team structure for HO, as providing twice the defences can enable a lot of setting up, with the main abusers being Calyrex-S, Arceus, Koraidon, Miraidon and much more.
A few replays of screens being goated in the recent AGPL.

C+ -> B+
Hatterene has risen up usage a lot, with hard walling more defensive mons like Eternatus and Gliscor, as well as beating stall easily thanks to it preventing hazards, and can have a slow piviot by the move Baton Pass. It can also run moves like Calm Mind, then Baton Passing it to various threats like Kyogre, Arceus-fairy, Miraidon and Calyrex-S. With Tera Normal, it can also flip the matchups again Calyrex-S, by taking little from Grass Knot thanks to it's light weight, making it only have 20 Base Power, while also threating with the move nuzzle to paralyze other pokemons. Thanks to Magic Bounce, it can also enable other items on pokemons, like Mental Herb on Arceus, Assult Vest or Life Orb on Miraidon, Rocky Helmet on Ho-Oh and much more.

C -> B-
As mentioned above, Dondozo is heavily limited by Electric Terrain to stop by using the move Rest in order to heal itself. Skeledirge on the other hand, has the move Slack Off to heal itself reliability. Thanks to it's natural typing, it can hard wall mons like Zacian-C, also beating Arceus and Koraidon in a 1v1.
Lastly, feel free to criticize this post and point out where I was wrong. Hopefully these noms would make sense.
