IC Kakashi uses kamui right of the bat, against the Gedo Mazo his reaction was using it right of the bat, against the Juubi his reaction was using it right of the bat, against that team of monsters his first reaction would be using Kamui right of the bat, so one of those 3 gets warped the first second of battle, you give Kakashi knwledge and he would know he has to warp Hashirama first.
Not to mention, if Orochimaru is not restricted, he can summon Edo Minato, who has BM at his disposal, and with Hashirama warped away team 1 doesn't have a LOT of counters to Bijuu atacks.
You are underrating team 2, if tsunade can give Kakashi chakra, he could just keep using Kamui while Gaara can make a sand defence to yasaka magatamas and etc...
Anyways i don't say team 2 wins but currently if you add Kakashi to any team you are giving them a solid chance against anyone.
