i don't think the fan is a counter to kamui and as for the PS, meteors, ect.. that's where kamui counters everything. there's a reason why Kishi made Obito have only one of his eyes. he'd be way too op for everyone. Naruto, Bee, Guy, Kakashi would all be dead by now.
I did not mean for to come off as the fan is a counter for kamui i am simply stating that he has the fan as we all know how powerful it is.
Kamui is good but the not the end all.If it was obito would be hanging that over his head instead of saying you need me to sacrifice my life.obit has the upper hand in the situation at hand which concerns madaras plan to be brought back through rinne tensei.
That however has nothing to do with a versus battle between the two.
In a battle between the two both have mokuton and a rinnegan that is where the similarities end. obito has kamui and madara has ems,perfect suusano and and all of hashis other justu obito doesnt plus he has the the technique obito already admitted to not being able to do nothing about a.k.a the meteor.
there is nothing to discuss if all your going to say is kamui.Kamui does not win the fight on its own its that plain and simple
