Hiruzen will solo him neg diff so kishi's keeping hiruzen away.
OT: I think Kishi should find a way to make the edo-kages dissappear or else he'll either have to increase maddy's power or downplay there power beyond kage levels.
Honestly it was fair bordering on good, minato should not be restrainable by zetsus wood (Ftg), once obito loses rinnegan he can't fight kakashi and minato. The shukaku part seemed canon
He's memory stays intact, and memory has been linked with chakra these days with the whole bump fist thing so, if he has his Chakra then he's got his memory.
This might sound like an attempt at trolling
But here goes. Madara might be able to spam endless izanagi/izanami with the fact that he can use MS abilities when he's does not have eyes.
