All-out fight in a deserted city (so lots of materials to use but no collateral damage possible.. keeps characters from holding back).

vs
Team 2
Ms. Marvel
Power Girl
Supergirl
Wonder Woman
Jade
Zatanna
Big Barda
(yes I know Z doesn't fit, but I put her in there to counter some of the Hulk wank. If it's better for you, remove her and Hulk and judge it that way.)
