use ninjas that chases to each other really well
focus on kisame as he will drain your chakra and you can't use any skills as time goes by. i passed that around 9k or 10k power?
welll i could suggest that you use hinata,karin/kabuto/neji, kakashi
when you use your skill then follows up wiith hinata (repulse to knockdown) will follow up then karin/kabuto/neji (knockdown to high) and then kakashi (will finish the combo) then choose your passive as wind style - vac* blast barrage (triggers at 10 hits)
let me know how did it go :)
