Hey, Mr. Uber. Ended up making two teams. Tried to restrict myself to mostly Uberfiend-core mons. Wanted to make a lot more but couldn't get the rest of the teams to work. Here's teams:
The Classic
Tried to use similar sets to your OG team, with a few modifications. Team is a bulky offense vibe, physical attackers only, with Brav as the typical lead, unless they're running Galvantula, in which case I'm auto leading Top. Trades well with a lot of the tier, opens up holes so the other attackers can clean up later.

- This is the typical Uberfiend suicide lead offensive Braviary set. Lead Brav every game, take a couple hits, watch everything melt to its coverage. Trading machine. We run Shadow Claw to adjust for the inevitable Rotom meta:
252+ Atk Life Orb Tera Ghost Braviary Shadow Claw vs. 252 HP / 252+ Def Rotom: 268-320 (88.1 - 105.2%) -- guaranteed OHKO after Stealth Rock
But also, it's just a strong move, 2hkos Bronzong, midgrounds certain mons, matches the "click strong move" vibe really well.

- Hazard removal with offensive pressure. AV is my preferred Top item most of the time, to match the special bulk, while allowing us to use maximum attack investment so that our Axels and Close Combats hit really hard. Underrated mon.

- Physical Metronome Meloetta. I replaced Psychic for Tera Blast, a STAB special move that can become physical coverage after tera. This can be anything really, tera steel to hit fairies, ground to hit poisons, so on and so on. Never got a single Relic Song sleep but she's here for the vibes.

- Munkidori check, anti-offense and win condition. I reckon you're a Qwil enjoyer from a couple early chats, so I decided to include him. Scale shot + SD snowballs really fast but you already know that.

- Rocks setter and trading machine. We run dual STAB + dragon tail to phase things we can't hit super hard. SPDef investment helps with surviving the inevitable specs neutral hit that's about to come in.

- Probably the most recent addition to your teams? Except I'm running my personal favorite set, which is resttalk physically defensive. It's been seeing a lot of success in NULT, checks all sorts of physical attacks including ladder's horror Rhyperior, takes Vaporeon scalds really nice, just a good mon overall.
And here's a few replays!

The Traditional
This variation is a bit closer to the type of offense I like running: Meloetta/Flygon form a specs/scarfer core that softens up walls in the early game, so that our win conditions - Diancie and Brav - can clean up later.

- Decided to go with a bulky setup variant for this one, not too unlike Tony's version. Sheer Force-boosted Body Slam is our STAB of choice, with Shadow Claw hitting the things Body Slam cannot. Beats the typical spdef Bulk Up Breloom sets because Breloom is a fraud, unrank immediately. EV'd purely based on vibes.
+6 100 Atk Life Orb Sheer Force Tera Steel Braviary Body Slam vs. +6 252 HP / 0 Def Tera Steel Breloom: 121-144 (37.3 - 44.4%) -- 32.1% chance to 3HKO after Poison Heal
+6 0+ Atk Tera Steel Breloom Facade (140 BP) vs. +6 252 HP / 152 Def Tera Steel Braviary: 73-86 (18 - 21.2%) -- possible 5HKO

- Similar AV removal to the other team, except we have sucker punch over bullet punch because I got tired of Chandelure.

- Running a choice specs set this time because that's my preferred way of running Meloetta. Hits really hard, takes hits really well.

- Meteor Beam Diancie, but on trick room because I absolutely do not believe in that rock polish set. It's so slooow and can't ever have HP + damage like trick room can.

- Speed control. I wouldn't dare running the other bird on this, so I'm settling for scarf Flygon.

- Physically defensive tank to match hitmontop's special defense shenanigans.
