A good counter for Electruxo-M?

[Nylon]

Hey, thanks for the thought. I'm already utilizing those movesets you mentioned above. But still, Electruxo is being neglected in this competitive forum don't you think? There's a guide for Metalynx and Archilles but Electruxo gets passed by...

Np!

What move did you put in the fourth slot?  (just curious...)

Yeah, Electruxo isn't getting a whole lot of attention   (kinda ironic since we're on a thread about Elec)
even though it's a fantastic pokemon that is easy yo use.

Oh, yeah... that's right. for those who didn't understand the 2-hit-encluding-my-self-canon, it means that it 2HKOs (if not 1HKOs) most things and is rarely 1HKOd
(meaning that at best it's usualy 2HKOd).

Surf. It is the strongest, most reliable STAB move I could find among Electruxo's movepool. Unless Rain Dance boosts Water moves accuracy as well, Hydro Pump is too chancy for me.

Surf seems like a good idea since you get 12,5% more damage.  
Hydro Pump is used a lot so I was slightly expecting that... But I myself prefer the better acc. over the higher pwr.
So, yeah. Hydro P. is not boosted by rain.
