VP, I'm thinking on building a team based around Mega Swampert and Zapdos (Disquake) for doubles. I need to put rain in there somehow, the problem is I don't think Politoed is the best option. I'm thinking on some actual rain dancers.

Also, what else would have good synergy with a core like that. I thought of the following:

Crobat
Zapdos
Swampert
Magnezone (with Magnet Pull and Magnet Rise)

Any suggestions?
