Arginine, florges, mega kangaskan.
Really, anything with mega kangaskan will win. I only list once against a faggot spiritomb that my kangaskan couldn't touch because mine ran sucker punch instead of crunch. Overall though, I think I picked great mons. A physical wall, a special wish passing wall, and a sweep your ass silly mon.
I suppose you could run Sylvain in place of florges but meh. I like florges better and it is slightly more specially bulky. Aromatherapy saved me a few times against toxic stallers. #rude
