I would run something like this with the shark summon. If you want to sacrifice, I would probably sacrifice Kakashi, or you can just wait until someone dies. Put this lineup and talents into the website and you'll see how nicely they combo together.

I would probably try and mess around with this team... Although, GNW Neji in the front means he will most likely die Round 1/2, but summoning the 1st Hokage with him will allow you to combo still (Just replace Neji on the website to see). It'll also allow Kankuro to have his puppet protected so you can get his mystery off. Otherwise, I would put Neji in the center below Orochimaru to protect him.
