A semi good set up I have used is Haku (Non edo tensei can be 3 stars), Zabuza, Wind main (Rasengan, Shadow Clone, Wind Dance, Queen Momentum/*y Harem Jutsu and Illusion Crow) with Kurenai. It seems to work as at 8684 power i beat the instance (Re-appearance of Ino-Shika-Cho) with a reccomended power of 9031 :D
