Didn't read, databook says that Kaguya is a kekkei mora user and Madara is not therefore Madara can't use kekkei mora techniques :bdpf:. Sasuke can use all rinnegan techs as listed for what any rinnegan joe can do, stay mad :bdpf:
isnt Databook say Temari can blow up the universe too ? :lol
the manga fact is the final statement, rinnegan with 9 tomoes opened on Madara forehead and then Madara cast IT then Kaguya was unlocked or hinted that she will be unlocked.... then Madara got stabbed by Black Zetsu so Kaguya can be spawned.
Read the time line, Madara had the most powerful eye and that 9tomoe are mathematically > 6 tomoe.
Since you like to using theory that never taken place before to Sasuke in the entire manga + extra manga, but you only assume his feats are based on the similarity of others, then by the rule you set, Madara can technically having feats of rinnegan with 9 tomoes from any other user that have the same eye.
You can not say this and then bite your own tongue later :lol
Just basic logic, you set the rule, you follow it, otherwise you are just invalid your self.
