Some noms.
C -> B/B+: Wrote about Chromera a lot in my metagame discussion post so I won't dwell on it too much here, but C is definitely underrating this mon for how good it is at breaking slower teams while possessing self-sustainability and a better Speed tier than some breakers ranked higher than it currently like Ursaluna. It does require some babying with its reliance on Tera and meh offense matchup, but if Ursa can get B rank while needing all that and more, Chromera is surely up there with it. Personally, I'd rank it higher at B+ cause its shown to have some level of versatility with the builds you can use it on and it still puts in consistent work if its tour winrate is anything to go by.
B -> A-: Hatterene does the same thing it does in OU and I don't see much in CAP that explicitly makes it worse outside of Equilibra existing for non-Mystical Fire sets. Even then, it sees consistent usage on offenses because Magic Bounce utility is just too good and... yeah that's pretty much it. Just think its underranked for a mon that's not much worse than it is in regular OU.
A -> A+: RUN MORE OFFENSIVE GREAT TUSK. It will change your life. For real, though, Great Tusk is just that guy and I feel its due for a small bump for how consistent it is at hazard removing and threatening a variety of the defensive cores used in CAP. Defensive Tusk sets aren't bad still, but the pressure that a set like dual STABs + Ice Spinner can put onto most cores that lack something like a Snaelstrom can be ludicrous especially if you go Booster Attack. Between that and the number of coverage lures it can viably run (Rock move for Moltres and Zapdos, Supercell for Snael) Tusk is always going to get progress done beyond just spinning if you use it right.
B- -> C: I didn't bring Epilogue in Seasonal, but goddammit I tried to build with it and I don't see how its ranked above C at all. On paper you've got the shiest Tinted Lens STABs and a typing that resists the most dangerous priority in the tier (Hemo and Revenankh moves) and that's amazing. But in practice, being forced to take Rocks chip nullifies a lot of the utility this guy has for offense and moreso reduces the chances of it ever getting a successful switchin to use Coil. Ofc you can alleviate this with hazard control but doing all that for a mid Speed breaker with frankly garbo bulk is never going to be worth it for me when there's so many better and more threatening sweepers to run in CAP. Keep it ranked for the occasional god matchup into fat, but other than that this mon SUCKS. Chuggalong also completely mogged this thing's potential niche on HO by being immune to priority, ngl.
Shorter ones now.
A -> A+: Broken and defines the tier. Lowkey could put it in S for that reason but at least A+.
B+ -> A-: Mogs the recent trend-up of mons like Tornadus-Therian and has always been good into a lot of relevant phys mons like Revenankh, Great Tusk, Zama, etc. Can be annoying for Equilibra to deal with if you run Heat Wave as well. The gap between this and Molt shouldn't be so wide.
B -> B+/A-: Agree with everything Lightniong said above. Shox is great.
C -> B-: Does similar things as it does in OU but you also get to be a soft Hemogoblin check for HO which is dope. Moth is also more relevant here than in OU which helps bring this up as a good option for your Screens builds. Feels a fair bit of a step above the ultra niche stuff in C except for like, Latias/Tomohawk/maybe Colossoil. Maybe rise those too.
UR -> C: Also mentioned these two in the meta thread but yeah please rank them, they're viable enough. Could argue Navia a little higher cause it does have a pretty legit role on offense as a Hemo check and status absorber but C's a good start.
UR -> C: You've got to really justify why you bring a Treads over Equilibra but there really are some builds where the higher speed tier and unique tools like Ice coverage for Gliscors/DNites or Knock Off being Knock Off can really work out. Use it as a faster kinda sorta more offensive Equilibra that spreads Knock and I swear it's worth C rank.
If you're worried about A+ getting too bloated with my noms, idk all those mons are goats. Maybe consider dropping Ting-Lu? Probably don't.
