@paulson3lt: Can Kakashi use it? I don't remember him doing it. Regardless, Asuma, even with Wood Release, is the weak link here. Guy and Kakashi both are above Kakazu, so he's out. Then with two on one, Orochimaru really can't win unless he finds a way to keep Kakashi worn out while avoiding kimui. Guy can punch really hard, but physical damage really doesn't matter to Orochimaru. So he wins if he can make the fight last a while, but if Kakashi and guy can keep him down for a sec and Kamui him, they win.
