Help me make a 4th gen Battle Frontier team

[sceptile33]

I'm trying to make a BF team made out of 6 Pokemon that can cover each others weaknesses in different situations. So far I have...

Garchomp w/ Yache Berry
Jolly w/ Attack and Speed EV's
Swords Dance
Earthquake
Dragon Claw
Fire Fang

Starmie w/ Life Orb
Modest w/ Sp Attack and Speed EV's
Recover
Thunderbolt
Surf
Ice Beam

Tyranitar w/ ???
Adamant w/ Attack and Defense maybe?
Earthquake
Stone Edge
Crunch
Fire Punch/Superpower???

I was thinking of adding a fighting type like Infernape or Lucario. Suggestions and ideas would be greatly appreciated.
