To use the Sharingan with kakashi you need to do a level 1 or 3 secret technique, to use the sharingan with sasuke you need to use a level 2 or 3 secret technique. With the sharingan you basicly become your oppenent only in sasuke's or kakashi's body. So all you have to do is move faster them them and you can win. The sharingan lets you have thier combos and chakra techniques (not secret techniques), to use the chakra techniques just enter the same buttons for a chakra technique as your opponent would. Thats a lot right there about the sharingan.
