I've really enjoyed this meta, and I made an account just to post this. With lucario gone, I see the meta shifting towards bulkier setup sweepers that can be very hard to stop due to their speed, power and frequent use of magic bounce. I found a nice little niche set that can force them out.
Pangoro with banettite gives you priority parting shot. This may sound OK, but when manaphy gets to +3 in one turn, it seems to come up short. The hidden trick of parting shot is that when it hits magic bounce, it's rejected back at the user, who takes the stat drop, while the opponent is randomly switched. This has saved me against calm mind blisseys and absol manaphys.
I'm on mobile, so I will leave most of the theorymoning to others, but I use some thing like project, drain punch, sub, parting shot. Obviously dies to pixelated speed.
Edit: Just to add to that, it also gets stuff like taunt, SD, bulk up, toxic, and even entertainment or torment if you want to mess with heliosk or catch espeeders on switch.
