Restrictions Preta path and no summonings
Location-Great Naruto Bridge
Who would win an why?
Going with Kakashi on this one
CT can be Kamui at the center where the core is
And without preta path Kakashi free to do his ninjutsu
Or he could put Nagato in Hell view
But Nagato can block most of his attacks with Shinra tensai
But Kakashi already knows about the interval, So he could use a shadow clone technique to cause the interval to start and then the real Kakashi can lightning blade/Headhunter jutsu
