How about Magnetric? Pretty much like Raichu, only better HP, Defense, Speed and Special Attack (lower Attack and Special Defense, but then it probably isn't using Attack and pure Electric isn't vulnerable to any elemental type attacks anyway).
Crunch(Egg)/Bite
Thunderbolt (TM)
Roar
Thunderwave/Charge/Attract(TM)/Double Team(TM)/Substitute (FRLG Tutor)
Thunderwave & Roar are the standard para-shuffler moves, though Static and Thunderbolt mean that you can still parashuffle with just Roar. Electric and Dark attacks give solid coverage - no single type is resistant to both, and the only dual types resistant to both are Grass/Dark, Grass/Fighting and Steel/Electric. Not too bad a set to deal with if you are forced to - none of them have an especially high Special Defense or Ground attacks (apart from HP Ground), so it is possible to beat them toe-to-to if you are forced to.
