A good counter for Electruxo-M?

[Dragonstrike]

Seems like it's Metalynx then. I really like that pokemon so I'd be happy to add one it to my team!

I breezed through Whimsicott and I saw it's offensive pressure against Electruxo-M, but,
I didn't understand how prankster worked in its favor. Sunny day? leech seed?
Well, regardless it dosen't matter. I see the offensive threat and that's good enough.
But, I might be naïve, but can an energy ball/giga drain (giga drain is the most common one I think) OHKO Electroxo-M?

Anyways, thx a lot for all replies!

Prankster whimsicott is moreso an annoyance than anything else.  Priority taunt, substitute, leech seed, tailwind, stun spore, grasswhistle...you'd be surprised how good a prankster pokemon with so many good non-damaging moves is (taunt, substitute, and the statuses are the really important ones).  Of course, Prankster Whimsicott isn't commonly used for much else, but it's not a super common pokemon either in main series competitive, as while it's annoying, it can struggle to pressure the enemy outside of those annoyances.  Same should hold for a non-mega Whimsicott in Uranium, really.
