Probably some of the most promiment faces of this type are Volbeat and Illumise. At the moment, they're the only Tailwind setter with the Prankster ability, which means at any point of the game, they can quickly set up this condition to control the field. Furthermore, they've got access to great support moves. "Paranoia", for instancce, is kind of cracked on these Bug Pokémon. For those who do not know, Paranoia is a special spread move that lowers the target's best stat by 1 stage and reduces its HP by 25%, similar to Superfang. This effect ensures Volbeat and Illumise will (almost) always be able to make progress against the opponent. It's unlikely that they become passive. An ally can greatly benefit from their disruptive potential to exert offensive pressure, which is further highlighted by their access to Encore, Light Screen, Helping Hand, and many other good support moves. Encore deserves special mention here as throughout the tournament, we saw a high amount of set-up monsters, notably Snorlax, Mudaimer, and Keisberg. Mauycaque and Fieratt further contribute to this development with Coaching. This makes Encore a very valuable move to have to punish the opponent for setting up. Thanks to Prankster, Volbeat and Illumise can quickly shut down those threats if the opponent isn't careful enough. What's more, in this PetMod, Bug Pokémon are immune to Powder moves, which means that, currently, there's no way to redircect this move to protect yourself from Encorre. There's no Follow Me user, and Rage Powder is a Powder move which gets ignored by Bug Pokémon.
To handle the pressure from Volbeat and Illumise, you could run some anti-priority techs. Farigiraf is one such example with its Armour Tail ability. However, it is very limited to certain teamstyles, such as (semi) Trick Room and doesn't appreciate tanking Paranoia or the influx of Dark Pokémon that we have here, such as Swampert-Rift or Cthulauder. In the finals of the tournament, I wanted to run a Hyper Offense Tailwind Team and relied mostly on Dark Pokémon to get around the aforementioned Bug Pokémon. Fwiw, Shiftry already neatly fits such an aggressive team since it can set-up Tailwind itself and exert good offensive pressure, especially with Wind Rider. There's no waste of a turn with it; it can hit immediately hard once Tailwind is set-up. Should it face some fast threats in or outside of Trick Room, it can always fall back on Sucker Punch. Besides, Grass/Dark is good into some metagame relevant threats, like Mudaimer, Swampert-Rift or Wizareetin-Gravelord, to name a few, and doesn't care about redirection from Rage Powder. Weavile, on the other hand, is more of a niche Pokémon but it does offer the fastest Fake Out, allowing Shiftry to reliably set-up Tailwind. Furthermore, it has a good match-up against Magikite, at the very least. Its ability to potentially break Focus Sash with Triple Axel is also quite useful. Then, there's Cthulauder which I consider a quintessential part of any Trick Room Team. Thanks to Contrary, the opponent can't lower its stats. Moreover, Cthulauder is quite physically bulky and has Superpower to quickly spiral out of control. I like running Leftovers on it to improve its resilience but other items are also quite possible. Samtendo09, for instance, used a weakness berry to make it less vulnerable to Bug. That's a smart decision since, again, we do not have a Follow Me user to protect it from Bug Pokémon. (Speaking of Follow Me, I might submit one that could fill this gap and be useful to the metagame. But I'll have to think about it.)
