Try to get tobi asap, then go,
Kakashi neji x
fire main tobi x
talents go, 33321 and summon gamachu.
You c*e this line up all the way till lvl 70, and you will be just fine (save your seals scrolls, to use in kages tresure).
ps: if you dont want to use this line up it's ok, but GET TOBI he is the best free ninja by miles.
