Hinata, Sasuke, kakashi - gives a 10 hit combo

Sasuke-kakashi clone- main clone
kakashi-Main-Hinata
x-x-x

on Shark aoe skill, chase: chakra blades, nuerotoxin, clone and Shark summon (Since u will get it soon)

Alternatively replace kakashi with Kiba,

Main-Main clone-x
x-Sasuke-Hinata
Kiba-beast clone-x

on 2 healing skills, chakra blades, clone, nuerotoxin and chameleon summon.

I find that these two builds work well for plot instances and survival trail.
