Still impposible for me with this formation and 16.7k pwr, lvl66.
Hinata's mistery on turn 1 is being completely ignored in 9/10 tries. If by some wonder she survives, bigger problem is that my guys simply can't start a combo. Usual combo start rate on Juugo is 1/30 tries. If point 1 and 2 happen, then karin starts in 9/10 a combo on my main, resulting bringing her to 50% hp. If by any means that doesn't happen, suigetsu starts 9/10 combo on hinata, either killing her or letting sasuke's chain to finish her. I couldn't do any better.
Simple math statistic formula says that i might get a good try in 190629 tries.
Or if i get 5 more levels and few k pwr more.
