Ok, I've been testing Pert on that team and its way better, it takes a lot of pressure off of Regi in terms of checking stuff which lets him do what he wants to do without having to worry about leaving yourself open to being wrecked by heavy physicals. Losing RS is pretty much a nonfactor, people have trouble just setting up Spikes and if they do it really hasn't mattered. I just 5-0ed a guy who used Cloy/Steelix/Gyara/Clops/Pert/Zap which should've been horrid for me. He even played well, double switching to get Gyara on Celebi multiple times and being conservative with Cloy to get 2 layers up instead of 1, etc. Only downside to Pert is WoW Gar, who will probably take a poke down and mangle another cause there is absolutely no check for it on there, but honestly for the most part Pert is better.
