well keep in mind that Kabuto's edo tensei is stronger because of A) the white zetsu and B) the human sacrifice. That's the main reason that the first lost to zombie madara. It's no wonder that the 4th and the 2nd aren't as strong as they would be.

Naruto really shined in this battle no matter how gimmicky it was he still used the element of surprise......even Sasuke had to go with it. Anyways let's see how they pull this off.
