i really don't see sasuke win this after minato got KB. that's right, why is everyone ignoring minatos KB?
alive minato should be capable of 5 KB. 5 KB = 5 minato. 5 minato > sasuke.
the weakness of KB are their low durability, but how are you going to hurt KBs if they have a fast base speed, shunshin and even ftg? add to that, that every KB carries hiraishin marks on their kunai, allowing minato and the KB to teleport to each other, it's impossible for sasuke to get a hit.
genjutsu doesn't work on KB. GG!
Im going to go with Sasuke i seriously doubt Minato could ftg there Susanoo off of them... If he could why wouldn't they just bring it back... Minato has no counter for Genjutsu and his Summoning will get controlled...
susanoo is a physical object and can therefore be warped away. the manga also proved that susanoo can be apart from its user. it's true that the user can resummon susanoo, but the time it would take to do that, would be enough for minato to kill the user.
