If anyone decides to chuck a run inti this category id recommend running a Summoning Jutsu. The kakashi clones will out number your team and therefore have a higher chance of overwhelming you in the beginning of each round. Prior to them spawning, use the jutsu directly on their spawn for instant damage and a disruption to their attack. This allows for you to kill one off quickly as well. For your secondary jutsu, id recommend something that can close off a distance quickly, as you dont want to be standing still very much with kakashi's kamui attack which will instantly kill you in the third round. I used lightning lariat so i could chain hits and get around quicker, but if you have trouble with it due to the slow charge up time, run leaf whirlwind or whatever else you like instead.
