Lead:
Yanmega - Modest - Speed Boost - Focus Sash - 252 Speed, 252 Sp. Attack, 4 Defense
Air Slash
Bug Buzz
Hypnosis

Yanmega is extremely useful in nuking a few pokemon himself often, and when used well is just an evil pokemon. He's just amazing

Electivire - Adamant - Motor Drive - Expert Belt - 252 Attack, 252 Speed, 4 HP
Ice Punch
Thunderpunch

Standard Electivire, super effective against many many types of pokemon
Togekiss (My favorite Mixed Special Sweeper) - Timid - Serene Grace - Expert Belt - 252 Speed, 252 Special Attack, 4 HP
Flamethrower
Aura Sphere
Air Slash
Psychic/Shadow Ball/Grass Knot (still looking for advice on this last slot)
Togekiss can learn so many moves it's great against so many types, and with special attacks against most types people usually don't expect a set this varied
Weavile aka Dragonslayer - Jolly - Pressure - Expert Belt - 252 Speed, 252 Attack, 4 HP
Aerial Ace
