good pokemon diamond battle tower team?

Ok so the title says it all, looking for suggestions on good battle tower teams in diamond, unfortunately i have no one to trade with nor do i have any gba game to migrate, so im stuck with whatever diamond gives me. my team is

Uxie@light clay

Psychic

Reflect

Light Screen

Amnesia

Azelf@mind plate

Psychic

Thunderbolt

Grass knot

Nasty Plot

Garchomp@Soft Sand

Crunch

Dragon Claw

Stone Edge

Earthquake

now i actually got past the tycoon, but i kno theres way better teams for this, considering i sumtimes had bad luck switching in and azelf would die or somethin would happen that would mess me up. so im jus lookin for any suggestions or teams for this thing. I also have staraptor, floatzel, infernape, roserade and luxray at my disposal
