Okay, I'm tryin to decide on a good M/S for this guy, but I can only think of this:

Jumpluff:
Thief<>Sleep Powder<>Attract<>Giga Drain
Sunny Day<>Solarbeam<>Hidden Power (Fire)<>Rest(Don't like this set much)
Substitute<>Encore<>Stun Spore<>Giga Drain

I don't know what to do. The 3rd one is what I'm thinking would be the best, but I don't know. He seems like he's UU, and I'm starting to think that it's for a good reason...
