A Midnight Blade friend I know uses this build and does alright.
Might be something to consider unless someone else knows anything stronger for the ninja you have available to you, but this is a start.
Have heals, 2 potential combo starters, some crowd control, heals, and couple clones every other round to soak up damage.
Not to mention Kabuto raises Kimimaro's Defense and Resistance each round as well.
Also able to hit quite a few targets every round as well.
Hope this helps you out. Maybe try it out a bit in Arena and see if it works for you first before investing in cultivation, mood, and awakening.
Oh yeah, and each character(bar-Kabuto) has a way to open a 7 Combo as well. Decent sustain from ANBU passive too. Main and Kimimaro deal TAI damage with their mastery skill and they are both AoE so will get quite a bit of Life back when doing that so long as you aren't ignited.
Anyways, good luck and hope this helped.
