If you scarf Evire you'd get a shitty 95 spd pokemon who can't switch moves, which is the main drawing point of evire, a free +1 boost to speed while being able to switch between various coverage moves. If I wanted to use a 95 spd scarfer with elec immunity I'd use Krookodile, who also has a good ability and stab pursuit.
Has anyone tried using meditate on Electivire? I've been thinking about it since gen 4 but never had a teamslot to use it. Basically, evire gets a spd boost from a electric pokemon, tanks a hit from the coverage move (probably HP ice) or forces a switch by threatening earthquake, and boosts it's attack with meditate. Afterwards, it basically has a dragon dance under it's belt and decent coverage with wild bolt, ice punch, and cross chop. Sounds good in theorymon, but it probably has issues.
