A good counter for Electruxo-M?

[Nylon]

There is another counter to M-Electruxo, but it may be more appropriate to call is a check, and that is Dunsereph. While not the strongest pokemon out their, it has access to incredible bulk to weather a hit and retialiate with Drill Run or Earthquake. While it can not easily status it (Curse you Electric Typing!), Yawn, Toxic, Taunt, and Swagger can quite easily force it to switch out, letting you set up for the opportunity.

Then their is its HA, Cloud Nine, which totally negates any and all weather effects. Send it out, change the weather and/or cripple/kill M-Electruxo, and bam, ruin their team set up (unless they have another weather user). It doesn't have the higest S.Def, though, and Thunder hits neutral against it, but with proper invest can survive a hit or 2 and do its job. Stealth rocks are a pain for it, though, so if they are out their, watch out!

I actually thought about duns once, but I immedietly stopped when I remembered that Electruxo-M always (ok... 98% of the time) carries
ice beam...
Electruxo is also faster. but I did never get as far as to consider duns being able to KO Elec with a ground move.
I'm a bit pesimistic to duns working but thx 4 the idea, I didn't think about it myself!
