sasuke could track juubito with ems and forced sm madara to block his sword in cqc. with his enton swords he would be able to incinerate obito's gunbai. sasuke is better at taijutsu than obito so once obito becomes tangible sasuke strikes him down. he should also be able to extend the length of his enton swords and change the their shape into something much less straight forward. i see sasuke winning scenario 1 med diff at best. for scene 2 sasuke's V3/V4 susanoo is much stronger than the gedo mazo physically. the gedo mazo was getting trouble for choji and his dad. and the lighting bolts from it won't even harm sasuke's susanoo. V4 susanoo lights gedo mazo up with hand held enton weapons never before seen and tanks anything it throws at it. im also sure sasuke's V4 susanoo could use an enton kirin and i don't see gedo mazo tanking that. sasuke wins low diff in scenario 2.
Not sure how he's going to incinerate anything when Obito simply turns it intangible just like he'd do to himself. The rest doesn't matter since you've failed to counter Kamui. Sasuke being better at Taijutsu is irrelevant when Obito is using Kamui and bukijutsu. Being better at Taijutsu isn't an auto counter for Kamui, and he doesn't become tangible unless he's about to warp someone away.
Not sure if I should take the nonsense in the bold seriously. Gedo Mazo fodderized Choji and Choza first of all. They hit it square on and it budged like an inch, then it's roar sent them flying a hundred meters away. Gedo Mazo is just as strong if not stronger than the Bijuu when it comes to physical strength. That's above anything but Sasuke's PS. The lightning bolts obliterated a Mountain. They obliterate V3 and damage V4.
Enton is irrelevant as it can't burn the Mazo, and Enton Kirin is fanfic. Kirin isn't going to kill the Mazo either. But Sasuke would be dead long before that happens. :lol
