I personally think team 1 wins, not because of KA but due to the fact that danzo has wind nature jutsu, which gives him the advantage against A, he also has a sharingan. For a matter of fact 11 of them, and that he uses izanagi. On a much minor note, he has a incredibly powerful summon and is very skilled with seals and curses. And last but not least, he has a mokuton defensive jutsu. And tobirama has S/T ninjutsu, Edo tensei and above that he is noted to be the best Suiton user in the narutoverse, including kisame. I really don't see where a close range and mid range character could counter these battle hardened veterans.
