Fire Itachi Sasuke Danzo is a decent 1v1 team. Provides 1st round shield and chaos disable + immobile from chase, and Sasuke can act round 2. Round 3 you kinda don't have much besides your second Itachi chaos though.

Fire Itachi Sasuke Tsunade is more suited towards team fights for the AOE healing. No point in running a barrier when Roshi will just break it by round 2.

Since you easily get high combo chases King of Hell is useful for the poison debuff.
