So Madara has planned most of this years in advance, it's a convoluted plot of awesome that boggles the mind.
He's smart enough to do that.
Yet dense enough to throw away legendary ninja tools, that he knows the name of, and thus knows the capabilities of.
It just seems inconsistent of his character...
Maybe you could say it's because he's getting cocky with hew newfound power but just...
It just seems like inconsistent asspull plot stupidity to me. It would take minimal effort on his part to use them or store them or even destroy them.
It almost seems like the newest chapter just doesn't fit the rest of the series, feels so out of place.
