Hello UU, i've been considering making a post like this for a while but laziness has gotten in the way...
With UULT being finished and my UUBD season pretty much finished too, i thought it'd be interesting to drop some of my reasonings (if there are ones for said teams) and my overall thoughts on the meta throughout UULT:
Laddering phase:
On cycles 1 and 2 i tried to cheese my way through with mostly rain and HO trying to get my games done quickly but it didn't work quite well due to me particularly not being a proficient user of said styles and once you got on the higher part of the ladder people would either be solid into it or at least know how to play against.
On cycle 3 i decided to just give up on that idea and build something i'd feel more comfortable using and that would be do better vs the teams trending in the higher part of the ladder. I tried a couple of different ideas, ending up trying sand builds just because of how sand rush excadrill is a big problem into most offensive builds and stuff like rotom wasn't that used at the time. After trying different stuffs on the ''glue'' slots, i came up with this final version that would prove to be consistent enough to get me a spot in poffs:
(i know people want to know sets/spreads so i left the importable available if you click on the image, i did try out different combinations and made some changes to use it later again so the actual paste might not totally reflect on the meta it was first used in, the most important change from the original one being the roar tech on cobalion to avoid getting cheesed badly by the stored power crown sets running around on ladder)
Playoffs:
Until playoffs my picks have been mostly pokemon that were already in the meta (aside from okidogi, which got a huge boon in popularity after me and udongirl using it a fair amount during laddering phase), it was the ''challenging'' part of the tour just because of how wide was the pool of stuff you could face in this environment, however, coming into playoffs i knew that while there certainly were creative players around, i could get away with using more off pick pokemon choices because players in tour tend to either reuse stuff and mostly sticking to proven meta picks, and that's where the ''unorthodox'' teams started being cooked...

(again, i did try to revamp those teams eventually so there might be some set tweaks from the original one)
Even though it lost g1, it was probably the first instance in recent sv uu where milotic was used in a tour, at the time being used as a check to battle bond gren check, stored power crown sets and belly drum azu, although certainly counterproductive with sand, but i really believed sand was strong just because exca on sand gave me an out for dangerous fast pokes while the idea behind scarf tyranitar was moreso that zapdos/tornadus would mindlessly click volt/u-turn vs tyranitar, which i could use as an opportunity to snipe them for excadrill/hydrapple.
The one pokemon that got notorious in this set was regice though, which i still think could be used although the meta where it was used first was more friendly for it for sure. Being a decent hydrapple + gren check while having a strong STAB that at the time there were not much good resists being used for it while getting passive healing through ice body was something that caught my eye when i needed to fix those weaknesses on the team i had.

For this week, we were at that point of the meta where ursaluna and crown started skyrocketting as threats in the teambuilder, so i decided i wanted to have decent measures vs them at least in one game. People were also not using spikes as much so i wanted to give it a try to see if i could make something work.
Even if my hazard users choice for rocks and spikes on this team ended up being weird on this composition, i think this combination worked better here just because of how limited empoleon is limited on moveslots and i feel like it doesn't wanna use rocks at all. While obviously you're not beating flame orb ursa with baloon pecha, it still provided a short term scout into it while possibly getting a foul play damage weakening it a fair amount to limit it to fewer opportunities later in the game. Regarding Empoleon's set + spread, i pretty much compressed it all there to check hydrapple, since you outspeed any non timid hydrapple and can either haze np variants or roost off leaf storms damage/threaten with ice beam.
The second team honestly didn't have a deeper thought on it other than just trying to abuse bulky setuppers, which seemed to be something most teams were having trouble dealing with. Originally i had enamorus-therian over zapdos but after Attribute trying this team out with zapdos to be a bit better into torn-T in the long term i liked the idea and made it zapdos too. Dragon Fang Hydrapple with this ev spread was specifically to drop most av torns with a +2 draco from full while surviving a bleakwind/hurricane from 0 spa zapdos, it felt kind of needed since i had no rocks user on this team so sticking up damage on torn was pretty hard in the long run aside from maybe dogi getting a poison on it. Vincune also felt pretty underrated and i liked it as an option here to abuse hydrapple teams running around at the time, and i still think suicunes in general could be explored in the actual meta although Scarf Hoopas popularity nowadays surely don't help much sub sets...

Despite popular belief being fat teams were pretty much out of the game with ursaluna being so popular, i tried to make a fatter team work (already started working on stall too...) and i wanted spikes just because with so many threats running around i wanted to at worse limit stuff i couldn't check properly, and the big breakers atm couldn't afford boots so spikes was guaranteed damage as long as i could get them up/keep them up. Some of the odds pick in the team felt needed just because your regular balance pokes admiteddly couldn't deal with the actual meta so stuff like sinistcha (for ursaluna + best spinblocker available to pair with gastro) + reuni (dogi check while still being able to threaten a wincon later on, which was optimized in merus version by just making good use of reunis support moves to potentialize its teammates more) + gastro (one of the most solid volt blockers into anything that is not grass knot thund, also helped checking gren) + skeledirge which at the time wasn't really looked at too much just because of how prevalent ursa was.
Admiteddly the Glaceon isn't really a good pokemon. Shocking i know. However the idea i had when trying to make use of it here was similar to Regice idea but with a more offensive approach since ice resists (actually freeze dry resists) were rare and slowking giving it a defense boost + accurate blizzards looked like a good idea for a breaker that also had reasonable bulk to get a sub on few passive pokes. Of course most remember how this game went though and Ursaluna took the show instead...

Since we decided to play pretty much when round went up i just picked three teams i already had built that i thought would be fine overall, obviously the first one was probably the worst one i've brought so far, specs ribombee isn't amazing and the supporting cast was just not helping it either.
Now going to the devil team, i was trying to come up with stall for a time by now since i think people just forgot its existence and claimed it to be bad throughout a good part of sv, and while i can agree with it not being amazing i do think it was still usable enough but needed to be optimized. Admiteddly i was having a hard time making one that i liked (obviously flame orb ursaluna was the biggest road blocker for it while stuff rising in popularity like okidogi certainly didn't help it either). I was looking through some games and i just remembered of
Tree69420 stall ihbst used vs me in UULT and i remember facing it on ladder in some other occasions and always thought it had a good base so i decided to work on that making my tweaks to my liking. I tried a lot of dogshit pokes just to combat Ursaluna but i ended up on Avalugg which ended up being the better overall option. It's not the 100% hard counter to Ursaluna but it gives stall pretty good tools to work with, being able to use Rapid Spin, has reliable recovery, funnily counters non meteor mash metagross and mamoswine which are usually two pretty hard pokes for stall while still being a decent Ursaluna switch, specially with Tera Ghost.
The last team was just me not having anything solid i liked left so i just decided to fall back on something i felt was solid even know Azick was my UUBD teammate and he had this team, which ended up on an almost mirror match where i got a lucky timely crit that decided the game. The team is pretty standard looking now aside from the obvious sinistcha pick for Ursaluna but at the time scizor wasn't the most common pick around but it had some nice utility by checking any non tera fire serperior via u-turn + hyperspace fury scarf hoopa, being able to pivot into mamoswine and being a possible wincon itself in the back

This was a week where i tried to make a couple of stuff work but me not having as much time this week + not really being inspired nor really feeling too much like playing (thanks
frankjosh for actually telling me to not total meme shit LOL) so i just decided to reuse some stuff i already had and work on them.
First team is pretty much the same one i used vs sabella with pecharunt over reuniclus, which was mostly to be a bit more solid into strong physical attackers that could overwhelm skele/reuni. Foul play tinka was mostly used as a tool to do more damage on excas/scizors/metagross coming on it.

Ironically the last two weeks were the ones i was more short on time and had to just reuse more ideas. It was fun how me and Mossy came up with the same Gligar idea when our teams were facing in UUBD LOL, and i'm glad people are starting to recognize it more as a niche but totally usable option on some teams.
As you can notice, all of the teams had the same gligar scizor dogi core which i found was good to cover a fair amount of threats in the meta at least in the short term. To no ones surprise Tentacruel team was a flop because well..... it had a Tentacruel. The main idea was compressing a faster gren check while mainly being able to use spin so i could free up a third slot on excadrill, which was something i wanted to use (sand rush specifically) since it gave me an out to Offenses/HOs given how my teams were fairly slow in general. Three attack Exca was used here as a way to try to take advantage of builds that were overreliant on zapdos to check it since most wouldn't assume rock move on it after iron head is revealed, paired with cb ttar so soften common checks for them.
The second team was mostly me trying to branch out a bit from some of the staples i was using and getting some usage on pokes that i haven't really used yet (belli serp latios), belli being a cope check to gren on this team while still keeping its ability to punish torns, serp being a soft exca check + can act as a wincon depending on the game state
The last one was just pretty much trying to use good pokes in exchange of having a somewhat more poor defensive cohesion, hoopa and gren comboing on defensive stuff so one can finally break out etc etc, nothing too fancy at this point
Post UULT + not used ideas/teams:
We have seen more people trying to push the meta's limit working on making use of more niche pokes that matchups well into meta trending cores which is always a nice thing to see to break the supposed ''staleness'' that many people claim to exist in UU for a good while (see the optimization of Milotic builds, Gligar, Fezandipiti, etc...). While in more top heavy metas the aforementioned problem can be true, i do think that in metas like this one we're having now (post luna ban) we can definitely afford to go a bit out of our way to experiment with new things. Obviously in this proccess there'll be trial and error like with most things in life, but that's the proccess to refine ideas that could pay off later on so even if some of your ideas don't work out it doesn't necessarely mean that other ''wack'' ideas also won't work out, as long as you do have a reason to go for them.
At this point in the post i'm prob too tired to go over all the not used ideas/teams but i'll make a quick list of stuff that i feel could be worked on by someone with more inspiration/just couldn't put enough time nor thoughts on them to make it work:
