Looks like you are running him physically based. Here is a great moveset and EVs that I have tried and it is amazing.
Sorry, but I won't give out EVs without moves. I recommend changing the moves, but you don't have to if you don't want to.
Eelektross @ Expert Belt / Life Orb
Ability: Levitate
EVs: 172 HP / 84 Atk / 252 SpA
Quiet Nature
- Thunderbolt
- Drain Punch
- Flamethrower
- Return / U-Turn
OK, T-Bolt is a good STAB, Drain Punch is great coverage and healing, Flamethrower is to hit grass and defensive steel types, and the last is pretty much a filler.
Hope I helped :)
