I have a brand new Elektross, and this is his moveset. Im open for suggestions, but I wanted one for the Battle Subway.
Hardy
EVs: 255 Atk, 125 Spd, 130 Sp. Atk.
Item: Choice Band/Life Orb
Thrash
Coil
Crunch
Wild Charge

Thrash is a hindering move, get rid of it for something else that hits for Physical Damage, anything is better then that...

If you are going to have Coil then get rid of the Choice Band possibility & as for my suggestions for the move...

Brick Break, Dragon Tail, Dragon Claw, Roar, U-Turn or Rock Slide...

Of those I personally would go for either U-Turn, Dragon Claw or Dragon Tail based on the rest of your team & personal preference...

Also, if you insist on keeping those SPATK EVs invested then go for Volt Switch instead as it does more damage & is only a problem to use on Ground Types due to immunity & this causing the effect to be negated...

That's all I got...

I was thinking of this after a while, for coverage. What do you think?

Item: Flying Gem
Flamethrower
Wild Charge
Acrobatics
Coil/Dragon Claw

Personal opinion on this is that Eelektross is much better off going down the Special route as opposed to Physical as your only decent Physical STAB gives terrible Recoil which something thats a little bit fragile like Eelektross doesn't want. If your not against getting a completely new Eelektross I suggest...

Modest/Quiet
252 Sp.Att / 252 HP / 4 Def
@ Leftovers
- Acid Spray
- Thunder Bolt
- Flamethrower
- Grass Knot/Brick Break

Acid Spray always lowers the opponents Sp.Def by 2 stages, so it's there to aid a sweep, biggest down side to it though is it doesn't effect Steels, most notably Ferrothorn. Thunder Bolt for STAB, Flmaethrower for those pesky Steels. Grass Knot with Modest, covers Bulky Waters and Ground types that clumsily get switched in because it's Electric. Brick Break with Quiet, only run if your in fear of Blissey.

If you want to run a Coil set, I suggest...

Adamant / Brave
252 Att / 252 HP / 4 Def
@Leftovers
- Coil
- Wild Charge
- Dragon Claw
- U-Turn / Crunch / Flamethrower

Adamant with U-turn / Crunch, Brave with Flamethrower. Last Move is just about what you need in your team, U-Turn can help keep you alive and lets you hit Grass types (Yay, thats useful), Crunch covers you for Ghosts and Psychics. Flamethrower for the ever present and ever annoying Ferrothorn.

Hope that helps...

Thanks. It's going to take me a while, but im just gonna breed a new one. Thank you for the ideas.
