Well the sword cuts through everything, even chakraWell, I can still b fixed..
Plus..
I have something he can NEVER cut through because NOTHING can get through it.. But it only lasts for 1 turn and its kinda weird to use THAT on a sword attack..
But i have something else to stop his attack..(not his sword slash)
We can't use genjutsu on him, and with that sword you can't rly use taijutsu (unless you're me in which case it's still pretty hard to get a hit), you could theoretically use ninjutsu, but Madara-sensei knows all the elements so he could simply block it and then counter.
What's left.... ummm.... sealing jutsu ??
I guess the only way to defeat madara-sensei (besides through ninjutsu, which is unlikely) is through a sealing jutsu.... but that would be very difficult still
Idk how to defeat him
But that's why he's our sensei, right, Zanji??
