First, completely forgot about Kakuzu.
Since he is Edo,he should not have his five hearts. He will first need to capture them first. Can he take them from Chiyo and Kimimaro? Repeatedly?
If so, even he can take out Hiruzen.
Jiongo underground can assist Kimimaro ad Oro.
Now that I remembered Kakuzu, I'm even more certain he dies quickly
Yo by the way I saw your request for me to bold the names in my introduction on the tournament thread (I was waiting until I could give you reputation to tell you this but then remembered I could just come here) but it's against the rules to edit your introduction after you've posted it otherwise I would have gone and done that.
You were supposed to be my sixth nom this month man, but i had promised i would nominate Troyse (and i never go back in my word, cause that's my ninja way...) My bad man, you'll be there for sure next month if you keep it up
