After the many weeks of NU beta following after Exploud's and Tyrantrum's ban, I believe this is or very close to be the most consistent version of HO Trick Room available with the current pool of mons we are able to use. For a while I've exclusively used this team and laddered around the top 50s with it so take what you will with a grain of salt. I had framed this after the infamous OU trick room skeleton consisting of 3 abusers, 2 defensive setters, and an offensive setter, and undeniably Cofagrigus, Uxie, and Audino are without a doubt, the best trio of setters of the tier in terms of consistent matchups amongst the current metagame. Beware of the very long explanation.
Diving into the setters:
Uxie is the only mon worth considering that has both stealth rock and trick room (Carbink has been tested and it's awful) because every team needs some form of hazards and momentum in the form of U-turn and Memento has proven to be a godsend for many trick room teams even in the higher tiers. Investment in the physical side over the special side as it's typing prefers it. Uxie's defensive capabilities are only better in NU as taunt is a little less prevalent in the tier which frees up space to run an item like Colbur Berry to ensure a safe setup against even a high damaging dark move such as an Absol, Houndoom or Sneasel. Uxie's all around bulk makes it a massive pain for any of the popular fighting types to muscle through (Virizion, Machamp, Toxicroak, Medicham, essentially anything short of a banded Emboar's flare blitz).
Audino is amazing at setting up trick rooms and eating attacks from almost all special attackers in the tier which makes it the perfect partner in crime for Uxie. Something like a choice specs Meloetta's hyper voice can only scrape the pink dino for half health before it can knock it off and render it weak for the remainder of the game and while nasty plot Houndoom pressures the rest of these mons heavily, Audino at any point can waltz in and possibly even tank a +2 never ending nightmare (a roll which is 66% in your favor) and set up trick room and Healing Wish to its next teammate. Not only can Audino take hits like a champ like almost no other Trick room capable mons can, it can simple switch in to a move, eat it up, set up trick room, and regen 1/3 of its health every time proving a constant pivot/nuisance to every special attacker in the tier. Healing Wish support is icing on the cake as it can essentially "revive" any of the hard hitting abusers back for another go. Magic Coat's slot has been tested over by things like encore, wish, toxic, etc. but the ability to lead Audino against a hazard lead with spikes or some other thing and protecting itself from a taunt, a sleep powder from the two quiver sweepers, or even making mental herb popping mind games much more difficult is invaluable.
Having tested many, many Cofagrigus sets, Nasty Plot/Shadow Ball/Toxic Spikes/Trick Room rises as the most superior option for around 80% games. We all know that Cofagrigus is one of the scariest mons people keep in the back of the mind when it comes to teambuilding and due to the rise of spdef Braviary and the constant popularity that Meloetta has attracted all this time, HP fighting is quite pathetic to what a Shadow Ball's capable of. So instead of running a second attack, opting for T-spikes over hp fighting has proved to be an amazing decision as it gives Cofagrigus yet another role in its insane role compression: Spinblocker, Sweeper, TR setter, and now hazard setter. Level 99 because this team awkwardly struggles with opposing Cofagrigus when the room is up without a few clever double switches (although Audino can eat a +2 hp fighting rather comfortably).
Explanation on the abusers:
Choice Specs Vikavolt absolutely shreds the entire tier from sweepers, physical walls, and even walls (most notably shreds physdef aromatisse) and comfortable seals notable 2HKOs and OHKOs life orb variants cannot offer while avoiding annoying chip damage. STABS are needed and energy ball rounds off by hitting steelix and rhydon ridiculously hard. Sleep Talk over any other garbage like HP fire so Vivillion or Jynx will get murked by STAB if they try to set up on it. There's just honestly next to no switch ins and often teams at team preview lose to this thing if they don't carry an electric immunity. Not much more explanation needed, hits ridiculously strong.
Flame Orb Machamp muscles through most of the tier and puts in work consistently in every matchup. Even the little things like being able to soak status and being a much needed dark resist for the setters make Machamp that much more of a desirable pick. Close Combat/Facade/Bullet Punch/Knock Off are undeniably the best moveset that we all know and recognize.
Choice Banded Granbull while is in my opinion, the weakest member of the team by noticeable margin due to Machamp and Vikavolt eviscerating the whole tier by themselves, is the best option for the last abuser slot. Not only does it have a great attack, a spammable STAB move in play rough in a tier full of few fairy resists, but it is also still useful outside when TR is not out and compared to something like Rampardos, Ursaring, or Marowak both of which I'd argue won't serve any use, something like Emboar or Crabominable which is just too similar to Machamp in the way in terms of moveset and purpose, or some random tech Ditto which is heavily matchup reliant. Intimidate puts a great stop on physical set up sweepers such as Virizion and aforementioned dark types that the setters struggle with. Granbull also acts as Machamp's backup plan if it gets worn down quickly as it can put out a respectable amount while not as much as Champ can. After swapping around the moveset for a while, Play Rough/Close Combat/Wild Charge/Earthquake covers the most amount of threats. CC is needed for the predicted Steelix switch and EQ is needed for the Garbodor switch. Wild Charge dents bulky waters like Jellicient and Vaporeon like no other move and oddly enough if you knock yourself out with its recoil, it provides momentum to your team funnily enough.
Closing Thoughts and Bad Matchups:
Trick Room in the current meta I'd argue is the strongest its ever been. Losing Exploud may suck but with Tyrantrum gone, the tier at least on the physical attacking side struggles to break through an Uxie and without Exploud, Audino can eat any special attack that isn't fighting with ease. I personally do not think it is matchup reliant either as the whole team OHKOs or 2HKOs the whole tier, rather annoyed by certain cores (Steelix/Jellicent or Steelix/Golbat cores are annoying but breakable with good prediction).

EDIT: OH SHIT THEY BANNED COFAGRIGUS NOT LIKE THIS NOT LIKE THIS NOT LIKE THIS. On a serious note, use Nasty Plot/Trick Room/Surf/Psyshock Psychium Z Slowking in place of cofag, it's LIT.
