Diglett chairs

this bothers me.. but diglett and dugtrio always pissed me off.. how are they so fast? It makes zero fucking sense and they always could fuck with my kabutops. He pwns all with a swift stream partner and possibly the best coverage in the game... toss in a focus sash/band so you don't need to sword dance and he's mean to anything that can't priority him.... except mimikyu... but that thing is just fucked up... a one hit shield for a an attack boost and a focus sash and a priority move and... who the fuck thought ghost pikachu could be such a jackass.
