My Rain Dance Team

I need some criticism on this. One of my friends on another forum commented that it could be taken down by a Ferrothorn, and I see that.

This form will look different, due to the fact it's an edited version of my team that I posted on another forum.

Finally, the reason why Ludicolo and Kingdra don't have Swift Swim is because on that forum, it's illegal to run a Drizzle+Swift Swim combo.

There's only 2 pokemon that set up rain dance, and I do admit Politoed is useful in that regard, but at least one more instance of rain dance would likely help....

That's what I was thinking along the way, I'll get to it.
