A good counter for Electruxo-M?

[Nylon]

Can't exactly brainstorm now, but M Eletruxo is also killed by..... M Archilles.

"WHAAAAAT??" You must be wondering if I'm joking, but I'm not XD

M Archilles outspeeds M Eletruxo and OHKOs with its Earthpower. I need calcs for Physical, unboosted Archilles' EQ against M Eletruxo, but it is close to OHKO it too. Either way, do remember that Archilles and Mega Archilles can run a mixed/Physical set as it has access to Swords Dance and Dragon Dance, of which the later is much more effective at running a Mixed set.

Anyways, you can throw in Archilles against an opposing M Eletruxo, Mega evolve it if that's your Mega and take away its rain, and just Earthpower/Earthquake it the same turn. Don't fret; Aqua Jet, even with rain, will not kill your Mega Archilles at Full HP.

It's a different story if Archilles is non-mega and gets a hit from Aqua jet though XD

I've thought about archilles too. And even though I completely forgot to mention it, it was one of the ones I thought had the best
chance.   But.   I got a bit worried how I'd get archilles swapped in. It is immune to electric... So that gives it an opening.
I think archilles is definetly a good choice, but it needs the right situation or else it'll be worth as much as Sunkern...
Though Archilles might really be number two after Metalynx, and, at worst u'll need to sacrifice a pokemon or undergo some risky
predictions.
Of course, there's nothing saying that Elec can't swap out, but lets not meake this any harder than it needs to
Thanks for reminding me! Archilles-M is definetly a good choice!
