I decided to go for something a bit different and I pretty much have no issues using this moveset.
Nature: Modest (SpAtk+, Atk-)
EV's: 252SpAtk, 252Spd, 4HP
Dark Pulse: STAB, chance to flinch, Ghost and Psychic
Flamethrower: Grass, Bug, Steel, Ice and Flying
Ice Beam: Ground, Grass, Flying and Dragon
Thunderbolt: Water and Flying
I know a modest Tyranitar sounds odd, but this moveset pretty much covers most types and you have the chance to burn, freeze, paralyze your opponent....oh and make them flinch.
If not, I also have the basic physical set.
Nature: Jolly (Spd+, SpAtk-)
EV's 252Atk, 252Spd, 4HP
Dragon Dance: Atk and Spd+1
Stone Edge: STAB, high critical hit ratio
Crunch - STAB, chance to lower foe's Def-1
Earthquake - Coverage
