So I've used this team and slight variations of it a few times on Pokemon Online and it's kinda stuck onto me since. It's my first shot at making a weather team and also my first OU team (I like UU better for some reason). I've really been wanting to use Rotom - W and I also like the VoltTurn strategy, which I know works pretty well in the rain. But mind you, VoltTurn isn't the main focus of this team. So without further ado, I present my team:
