[REQUEST] Counters to Rain! (Help needed)

[Pokeventurer]

Hi guys popping by for a small request from all you guys. this time i am asking for counters to well defined rain modes. i know that i'll be able to put up some text but it still won't be all, all i can think of now is mega venusaur and thunder wave really, but with more heds than one combined can give away better ideas.
the reasons i am asking this for is that i am writing a post regarding an analyses to rain for his site and my blog too, so i was hoping that you guys could help me don't take anything mentioned in this post as a personal target or attack nor am i tending to insult someone or something in the site's community. i get some negative approaches many times, so just saying it for that.
