Surely han in front of naruto (if you use the mystery after bee gave yo! to naruto) helps because denies the CD reduction of naruto mystery wholly. The problem is what ninjas to add to him to make actually the team work.

I tried for example to use full healing team + han but somehow i feel for it to work hokage tsunade as the 3rd healer or tsunade sannin war with breaktroughs are needed (i don't have hokage tsunade, tried with kabuto and i saw i missed some healing to actually overcome the damage i endured in later rounds).
