To be fair, seems rather easy for Cinccino to become better than Maushold, all it needs it Game Freak give it Population Bomb and boom, Cinccino becomes a decent threat in OU.
Better coverage and more attack and speed. But maushold is a bit bulkier, which in some cases does come in handy for taking a hit.
There are no obvious bans in the tier, but with some cooking some stuff might come out. DD Gouging fire and SD Iron Boulder are specially powerful, but do have some struggles, still I feel there is a lot of potential with tera within them.
CM Latias is extremly good in this meta and legitly easily 6-0 most teams. Cant believe some people believe Latias could en in UU
Latios is mostly a weaker alternative to Dragapult, but with less power and some extra utility.
I already said it a few times, but yeah, Darkrai is very mid, not enough speed, hypnosis isnt reliable and without NP it does not really hit that hard. Cant slot coverage for everything and gets KO by too much stuff.
