Most Meowscarada are U-Turning until they can clean up with Flower Trick tbh. A resist berry seems completely pointless, as a lure option for Meow is kinda the antithesis of what you want it to do.The only resist berry that would make sense running on meowscarada to me is whatever the ice resist berry is, since if you're staying you're 9/10 clicking flower trick and turning monograss, and the berry could help you resist... chien pao icicle crash? maybe? Not sure, I'm already hurting my arms with stretching here.
I haven't used meowscarada a lot, but the few times I did I preferred scarf to get the jump on booster energy iron valiant and other scarfers. Don't take this too seriously though like i said, I haven't used the cat much so I'm just going outta my limited experience lol
