Woah. Okay so imagine a three way split evo keeping the Electric one as a normal level up.
Expose it to a Fire Stone or a Metal Coat/Ferro Stone yields either a
>Firebrat that is unsurprisingly Bug/ Fire or a
>Silverfish Bug/Steel (bad DEF but decent SP DEF, speedy sweeper build)
Admittedly piggybacking off
>>34511187. But is think I'm onto something. Even if this is a wormadam style evo, maybe Level Up holding X Stone with a town that mines Electric Stone fragments to power the town. And Electric mining town that has Ground types nearby but the Electric types are slightly over leveled and nothing to scoff at because of coverage moves
