Rampardos is honestly the reason why Webs teams are as dangerous as they are. Rampardos is the hardest hitting non legendary pokemon, of course it's going to be somewhere near the top. Being able to destroy all the hazard removal options in the tier and also everything else is unique only to Rampardos. There's not a single mon that really wants to switch into this pokemon. It's obviously held back by its abyssmal speed and lack of bulk. Rock Polish is also a scary wincon but Relicanth ends up being more consistent despite the huge power difference thanks to its superior bulk.
