The other run I did with Clefairy instead of Kukui was impressive, but I think this team is more consistent. One thing I forget is that Accelerock flinches are much easier to chain than other flinchers / sleepers. No idea why that is, but it's certainly a nice mechanic to abuse. That's why I can flinch on turn 1, and then immediately attempt the flinch on the right side.
Once they have the Resilient status condition, Kukui can take this time to Leer or refresh Accelerock. After Primarina buffs, you can go for some Sing RNG, and even it fails / misses, you might activate his move gauge passive.
The run in this video had really good luck. You will definitely have to reset for RNG a lot, but if you know how to abuse flinch / sleep, you can skip a lot of turns. Very lucky to keep two alive at the end.
