Well i used rapid spin to stop those stall teams that use roar and such to rack up that entry hazard damage cause i have battled quite a bit of people who just roar over and over. I also just like to get rid of those entry hazards as in uu theres a lot more toxic spike users. And id rather not have my pokes poisoned. I might change roar to rain dance because of those hail teams that can rain on my parade. And also there are some evolite hippotas that ive seen.
