I just realized something: Wormadam-S can also run a Rain Dance support set, and it lures in Fire-types like crazy. I probably wouldn't have realized that if you hadn't made a Rain Dance set for Wormadam-G. Once I finish with my current analyses, I might reserve Wormadam-S.
May I take over your Wormadam-G update, seeing as it hasn't been worked on since August? Of course, I'll post a link to your original thread. It's got one stamp already, so I believe it can go through QC quickly. I can handle two QC updates at once (the other being Piloswine, which I've almost got ready), and the GP stage for Hypno and Dusclops is easy.
It does have a freaking MASSIVE movepool though. As far as decent options go, there's Trick Room, Memento, Destiny Bond, Toxic, Taunt (for use AFTER TR) and lolGravity. It can't really go offensive, and it somehow doesn't get Trick D:
