All are at there prime and not near death
Round 1: All are bloodlusted
Round 2: Same but Orochimaru gets 3 days prep
Bonus Round: All except Sakura on Team new legendary sannin are restricted to pre fourth shinobi war feats so essentially Sasuke has no perfect susanoo and Naruto is not at the point where he fully cooperates with the kyuubi so he can only use the first stage of KCM.
Genjutsu is allowed but Tsunade can snap her team out of it immediately
Win by BFR, KO, or Death
