Here, I'll get you started:
-Snorlax w/Assault Vest
Nature: Adamant/Careful

EVs: 252 HP, 40 Defense, 212 Sp.Defense
Moves: Return/Body Slam, Wild Charge, Earthquake, Crunch
-Blissey w/Leftovers

or
-Porygon Z w/Life Orb
Nature: Timid
Ability: Adaptability
EVs: 252 Sp.Attack, 252 Speed, 4 HP

Or for pure lulz, give it Hyper Beam and a Normal Gem
-Heliolisk w/Leftovers or Life Orb
Nature: Timid
Ability: whatever floats yer boat
EVs: 252 Sp.Attack, 252 Speed, 4 Defense

I think it'd be better to use Staraptor instead of Braviary:
-Staraptor w/Choice Band or Life Orb
Nature: Jolly/Adamant
Ability: Reckless
EVs: 252 Attack, 252 Speed, 4 HP
Moves: Brave Bird, Close Combat, U-Turn,
But if you really really wanna use Braviary:
-Braviary w/Choice Band or Choice Scarf
Nature: Adamant/Jolly
Ability: Sheer Force/Defiant
EVs: 252 Attack, 252 Speed, 4 Defense
Moves: Brave Bird, Return, Superpower, U-Turn
or
-Braviary w/Leftovers
Nature: Careful
Ability: Defiant
EVs: 252 HP, 192 Sp.Defense, 60 Speed
Moves: Bulk Up, Substitute, Brave Bird, Roost
And I remember Ursaring being fairly good.
EDIT: Dammit, I got ninja'd again. Guess I type a bit too slow or something. I still say that Staraptor should be used instead of Braviary.
