Unconventional strategies?

What are some of the most enjoyable uncommon movesets you use for competitive battling?

I'm really digging Sturdy Aggron with Thunderwave, Stealth Rocks, Iron Head, and Dragon Tail.

Thunderwave, lay rocks, then either Iron Head for a keeping them flinched and paralyzed, or Dragon Tail to make Stealth Rocks bite into another Pokemon, so I can promptly Thunderwave again. Makes a pretty solid lead, and it's great for when the opponent leads with a baton passer, or other setup. I can let them set up while I Thunderwave them, and get Rocks on the field, and Sturdy helps make sure I can get a Dragon Tail.

Leftovers as item, but I'm open to other suggestions. Also, any creative ideas for using Raichu? Poor guy is so underutilized.
