I have problems too repeat it over and over for 4 to 6 hours trying to pass, formation, comps, etc. one by one, this worked for me, I was Level 46 and had 6600 ish power and I could pass it, so can you.
I will explain detaily my jorney on this.

My strategy was :
1- First turn using hinata (neji too fast to cancel and if you do, you'll sorry the next turns, and if you change the position to cancel him or lee that would be just bad), neji would use a*pure on hinata but hinata is too fast for him, so no cancel.

2- Second turn use kakashi on neji, to kill him, a full combo that star with kakashi oneshot him (lee too but you need to kill neji first, acupunture and long combos thanks to him) guy would try to interrup but kakashi is too fast, use earth interrup on guy is very crucial (kaka is too fast for guy, but if you don´t interrup him, he would oneshot kakashi).

3- Third turn just focus lee and the rest should be easy, and that's it, sounds easy but it doesn't at all, it cost me, was too hard, too exhausting, and too frustating and put me to my limits (thinking the best way to do it)

PS: If you are lucky your earth main or could pass neji's passive and start a combo, whoever does neji woul be death, then you can kill lee with kakashi, that would be two death in two turns.

PSS: That's my main comp by the way, and it worked at last, I heard neji is pretty good against them, but I couldn't make him work, this was my experience and how I done it, I hope it helps you
