Rises
A- to A Agree
Serves a lot of utility and the metagame is kind it to it. Dodrio being in the tier, Articuno, Roselia and Togedemaru rising in usage, very versatile mon too. It can run flyinium z, stallbreaker, defensive. It has a great typing both offensively and defensively and not many mons resist it's stab. It's good against the common rockers like Mudsdale and defensive Mesprit (To a certain extent).
B- to B
The best answer to hard hitting special mons like Sensu, Mesprit, specs Jellicent, Aurorus, Lilligant, Omastar, Alolaguttor, Raichu, Haunter, Ludicolo even under rain, the list goes on. It has Protean too, which boosts stab and being normal type from the bat is great to get neutral damage from most attackers, even it can tank Focus Blast from most mons that learns it. It has a great movepool too. Besides Drain Punch, the 2 priorities and knock, has some overlooked moves like the elemental punches or fake ou. AV is just more splashable than before, and even it can be walled by mudsdale, still a great mon.
B+ to A-
It just gotten better. The rise of Mudsdale and the fact that it hit hard, it has a great typing offensively, barely resisted by the metagame, it is quite unpredictable (being physical or special), has great coverage (focus blast to hit alolash,stabs grass/ice, eq, blizzard 100% accuracy, wood hammer, ice shard), it can serve as a support instead of aurorus if you really want that extra speed and better coverage and priority, or leech seed. As I said, barely nothing resists a blizzard paired with giga drain/energy ball, focus blast or the mixed physical biased set. The only mons that resist that combination are bronzor, articuno and maybe crab? (if its run mixed that's another thing). It cann revenge kill some threats like lilligant or sensu/pom pom after some chip with ice shard. The downsides are that it is still slow, weak to sr and easily revenged killed, so I think A- is a good start.
C+ to B-/B
It has a great typing, great bulk with eviolite, can fit into most stall teams and can stop mons that threaten their teammates like the normal twins (Stoutland and Kangaskhan), Dodrio, lilli, etc. It is annoying to deal but it has problems, like reliaying on psywave to deal damage or skuntank still prominence, Jelli dropping from NU, and being completely passive, but it is actually better right now.
I wanted to nominate Frostom to A- but I think it's too early, for now.
Drops
B+ to B
Dodrio's drop didn't maked it any favor, Articuno's rising in usage, being still slow after a quiver dance, Frostom rising too, the oricorio's brothers being that good, lilligant existing and being faster, needing like 4 quiver dance to really sweep, requiring a lot of support, Froslass existing, same with togedemaru, it's just not that good to be in the same rank as Crab, Alolachu or Alolasian.
B+ to B/B-
Mudsdale existis, also better ghosts that are pretty common, not being that bulky or fast, only strong, but there are far better options, and one of them is not relying on shadow punch for stab. It has good coverage, but it's just too weak and is walled by common mons like mudsdale, poliwrath or defensive jelli/mesprit, because shadow punch is underwhelming. It is outclassed by a mile by mudsdale as a stealth rocker defensively, and if you want to spinblock hitmonchan or alolash, just use mudsdale with another ghost type that can support better the team.
C to D/Unranked
Why is this thing still ranked? It's just a bad dodrio. It doesn't have anything that dodrio already has. Bullet Seed? still doesn't do enough damage to regirock and good luck using that against mudsdale. Brave Bird? dodrio has that but it has also a great speed tier. The only thing it has to rely it's boomburst, good luck using that against Eelektross or Jelli, or even better, mudsdale can tank it. Same thing, articuno's rising doesn't do it any favor, same with PomPom. It can learn SD to, I don't think it is viable at all in this mon. Too slow and weak, and has nothing to do as a wallbreaker when stoutland, dodrio, scyther, kanga, aggron exists.
