Ninja Exam level 95 Fire Main Hinata*5, Kankuro*2, and Tobi*4
Strategy Round One: Use Hinata's mastery skill and pre-target Kakashi. Wait until Kankuro uses his standard attack and use your Main's mastery skill during the animation of it. Target Guy and wait for the next round. (Go ahead and reset if Hinata is below half Life, Asuma resists acupuncture, or Kakashi resists the sealing jutsu.)
Round Two: Quickly use Kankuro's mastery skill on Guy. (With any luck this should hopefully kill off Kakashi's Water Clone making him open to being slept by your Main.)
Round Three: Use Tobi's mastery skill on Guy once more, this needs to kill him. Asuma should be dead by now or 1-2 hits from it. (It kept getting messy around this part for me as Guy is a madman and kept ripping my Sasori/Main apart.)
Round Four and Beyond: Kurenai is going to shield whoever has the lowest remaining life on her team, I'd personally suggest trying to take out Kakashi first if it can be helped. It's pretty straight forward otherwise at this point, just do what you can to finish them off and hope Tobi decides that dodging is a good idea for when Kakashi wants to use his mastery skill on him.
Final Notes: Ok...so I'm going to save you guys a headache here. Please do not try this below at least 27.5~28k Power. I completed this at 26.2k Power myself, but man did it bother me. I nearly gave up after at least 2.5Hrs of resetting over and over. So I'd say at the very least try at 28k Power. I will note the stats of my ninjas below.
