I've been using stall to great success, hitting rank 1 for a bit before falling off (on the account "the 2nd clawming"):
eternal hell prison stall
Let me go over the team real quick:

@ Heavy-Duty Boots
Ability:
Volt Absorb
Tera Type: Flying
EVs: 248 HP / 8 Def / 252 SpD
Calm Nature
IVs: 0 Atk
- Revival Blessing
- Rest
- Discharge
- Sleep Talk
The star of the team. Defensive pawmot reaches insane level of bulk in BnB, standing at a whopping 140/140/120. This lets you use the forbidden strategy: RestTalk + Revival Blessing. Revival Blessing is supposed to be limited at 1 use per game (or 2 with leppa berry), but Sleep Talk is able to call it. In the real world, this is very difficult to abuse because Pawmot is not very tanky, but in BnB land, it's very easy to do. Volt Absorb over Natural Cure might seem like a strange choice, but it's actually inconvenient to wake up whenever you switch out for the intended purpose of Sleep Talking into Revival Blessing. It also lets you prevent other Pawmot from clicking Volt Switch to gain momentum. Lastly, discharge is your offensive move of choice as it lets you paralyze taunt users to be faster than them, and deals actual damage unlike nuzzle.

@
Choice Scarf
Ability: Levitate
Tera Type: Steel
EVs: 252 HP / 4 SpD /
252 Spe
Jolly Nature
-
Lunar Dance
-
Trick
- Zen Headbutt
- Moonlight
My secret tech. Cresselia doesn't get any stat boost in BnB (except attack, which lets you pick up a few surprise KOs with Zen Headbutt in a pinch), but it fills a role no other pokemon can. Combined with Pawmot, Cress lets you infinitely restore every other pokemon on your team to full health and PP, which theoretically lets you keep on playing
FOREVER (as long as Pawmot doesn't die, or Lunar Dance PP doesn't run out). To do so, you simply click Lunar Dance, heal up whoever you need to, then revive cress with Pawmot. As a funny hilarious bonus, you can use lunar dance on Pawmot, which restores Revival Blessing's single PP, letting you use it immediately to revive Cresselia without needing to call it with Sleep Talk, and this cycle can be repeated infinitely as long as you can find a way to switch back into Cresselia. Trick can come in handy to force progress versus other defensive teams, but mostly Choice Scarf is just there to get the fast Lunar Dance out every time.

@ Leftovers
Ability:
Pressure
Tera Type: Poison
EVs: 252 HP / 56 Def / 200 SpD
Impish Nature
-
Cosmic Power
-
Knock Off
- Night Shade
- Recover
This guy is just bonkers tanky. It's funny to think that in Godly Gift, you can use this with 150 base hp (passed from Giratina), but the meager 100 it gets here is more than enough to wall pretty much everything that doesn't hit it super effectively. Anything you don't outright wall can be walled after 1 or 2 cosmic powers go up. This is also the team's best progress forcer: You can remove items with Knock Off, force damage with Night Shade as normal types are not all that common, and stall an ungodly amount of pp from everything you can't beat normally with Pressure. Usually this would be limited by it's own recover pp running out, but thanks to Pawmot + Cresselia that is no longer an issue :))

@ Leftovers
Ability: Regenerator
Tera Type: Dark
EVs: 252 HP / 20 Def / 236 SpD
Impish Nature
-
Haze
-
Poison Jab
-
Infestation
- Recover
What stall is complete without a Regenerator pokemon? Pex is much of the same as deo-d, but in a different flavor. This lets you haze any pesky boosters, and trap defensive pokemons with infestation to force damage/pp waste. I went with Poison Jab instead of Toxic or tspikes to be able to poison taunters. There's honestly not that much to say about this one. Dark Tera is there to stop from losing to psynoise/stored power, but honestly it might not be needed as Deoxys-Defense will wall any stored powerer to shit. I've had him fully stall out a Farigiraf who was at +6 special attack, special defense, speed and +2 attack (that's 420 base power) just by boosting defenses alongside it then spamming recover to waste all stored power pp (it was doing a measly 48...). Anyways, moving on...

@ Heavy-Duty Boots
Ability: Sturdy
Tera Type:
Water
EVs: 248 HP / 8 Def / 252 SpD
Careful Nature
- Brave Bird
-
Spikes
-
Whirlwind
- Roost
A little bit of hazards speed up the process greatly. Sadly I couldn't fit stealth rocks on the team, so I went with mono spikes. Skarm is insanely bulky just like everyone else, and having whirlwind in my toolbox is a more than welcome addition. Just like Pex, I don't really have anything to say about this guy. He works just like Skarm does in regular play, only he's 10000x times bulkier thanks to having it's hp and spdef doubled. Tera Water is very helpful against Rain and Sun teams.

@ Heavy-Duty Boots
Ability:
Neutralizing Gas
Tera Type: Ghost
EVs: 252 HP / 252 Def / 4 SpD
Bold Nature
IVs: 0 Atk
- Pain Split
-
Defog
- Will-O-Wisp
- Strange Steam
The "best" hazard control in the game. Gholdengo is probably not all that common, but it's good to take precautions. Besides weez-g, much like Skarmory, gets its HP and Special Defense doubled in this tier, making it soooo much harder to deal with. It's also a full counter to Corrosion Salazzle, because toxic will fail against it thanks to Neutralizing Gas. That ability in general is pretty useful, making it a good lead against weather teams for example. I prefer strange steam over sludge bomb just because it hits pawmot super effectively.
Playing this team, I did lose a few times to very offensive teams and one time to Rage Fist Primeape + Resttalk Pawmot (which I think I could have won if I just played it more patiently), but it's overall very solid imo and playing it for so long has led me to believe that
maybe Pawmot or at the very least Revival Blessing should get banned. It's not a very healthy presence for the tier in my opinion, and while there are ways around it, it just enables a lot of smelly cheese.
Last but not least, here are a few
