A good counter for Electruxo-M?

Whaaaaaaaaat? You guys don't know? Water moves are boosted under rain. That includes Hydro Pump. 20% chance is still something to consider though, so be careful.

Same goes with Sunny Day. Fire moves are boosted in the sun.

Actullay I did mention that it does get boosted.
But I guess what you misunderstood was the quote:
Hydro P. is not boosted by rain.

What I meant was that the acc. was not boosted.
In comparison, Blizzard is boosted to 100 acc. from 70% when there's a hailstorm.

So it was a misunderstanding.
But thank you!
We might not have known, and in that case we'd be happy to know.
