hmmm i dont know jugo in v2 form would be 2 much for sai & sakura. But i need to see more of sai's techniques rather than him just summoning monsters. And a few taijutsu tech's also jugo v2 against sakura would be overkill. So sai would end up sacrifcing him self to let sakura land one of her monstor taijutsu moves which could be equivalent to raikages lighting elbow or watever or just below imo. But sasuke would probably intervenes amaterasu sakura done but naruto would use plot hax to save he kakashi finishes of suigetsu with mid difficulty. Then its just saksuke EMS vs KM naruto and MS kakashi.
Kakashi dies in the edge but it also gives them the edge in winning so team 7 FTW
