Asuma, Sasuke, Guy and Main. Talent 3, 3, 3, 1, 2 with Chameleon summon (still waiting patiently for that King of Hell). Set up Sasuke's barrier first, then hit the fox when everything you got. Because of main and Guy's leeching skill, your Hp will almost always be full, so Asuma's buff can kick in.

Right now I'm experimenting with GNW Tenten and Sage Naruto but the team is still iffy. Will let you know if something else works.
