Many of those pokemon can be out to good use.. Machamp, solrock, Rhydon, Aggron and especially medicham are good with choice band.

Muk is quite the tank with curse and can take an alakazam psychic.
Lunatone is always good with cm/psychic/ice beam/something
Pinsir is good as it has the ability hyper cutter(sp?) and swords dance..
Exploud can be excellent with ninjask. Hariyama is good with bulk up/whirlwind.. Tentacruel can be good, but i've never seen it work.. it completely owns ludicolo though. Donphan is godly if you bp to it with ninjask.. at least i saw something like that once.

Electrode is not that good anymore as it's no longer the fastest pokemon.. Sharpedo is almost too weak defencively to use. Seviper is just bad. Crawdanunt is also not too good..
