In sand however switching into spikes and rocks to spin eventually wears down the spinner considering the fact that Starmie is the only spinner with reliable recovery, and it's very frail. That means the the damage done could lead to an easier KO.i agree using gliscor > skarm like stated because because you dont have spin blocker =/
I would strongly consider Gliscor if I had a direct counter to Haxorus.
I'm still testing things out however. I've been using Terrakion in Dragonite's spot and might try out Gliscor next.
