I've been laddering a bit throughout this month and my opinion hasn't changed that much since last time (around 2023 I guess).
I've tried many playstyles such as HO with or without Aurora Veil/terrain, bulky offense, Trick Room but I think there is one archetype in particular that is very, very good : hazard stacking semi-stall teams.
With things such as

/

-

/

/ -

/

-

/

or

/

you can basically check most of offensive threats (

/

-

/

/ -

/

, etc.), put pressure with rocks/spikes/salt cure in return and find the good opportunity to set your wincon (

/

-

/

etc.).
So what I've find out is :
1. Stop relying only on Rapid spin, or consider having both rapid spin + Defog/Tidy Up/Court Change (

/

-

/

-

/

-

/

-

/

, etc.). Spin block is too easy in this meta so make sure to be prepared against hazard stacking.
2. Substitute /Taunt can really make a big difference in your offense strategy, don't only rely on strong and powerful moves. I've been trying

/

with Substitute and that can be annoying against passing walls. You may need Knock Off along Liquidation/Superpower to get rid of Rocky Helmets.
3.

/

is a good solution to weaken defensive cores : Knock Off and Drain Punch will creep most of Regenvesters with max Spd, while BoltBeam does good damage to physical walls. It can also absorbs status that would creep your team.
4. Should you have an issue with Triage, you can consider

/

since it neutralises Triage and is immune to Stored Power. It can also support your team with Rapid Spin, Knock Off and pivot with U-Turn. I'd add this to the VR as a viable option.
4.

cannot inherit but it's already good in what he does : ignoring Unaware, Ivy Cudgel, recovery with boosted Horn Leech, access to lot of utility moves (Encore, Spikes, SD, Taunt...). I personnaly ran SD/Ivy Cudgel/Horn Leech/Trailblaze with Grassy Surge support.
See you!
