Ninja Exam level 98 Fire Main Hinata*5, Kimimaro*4, and Kankuro*2
Strategy (Quick Note: This one is similar to Exam 97 really, use your Main's Sealing Jutsu a bit sparingly for best results. Idealy you want to use it to restrict damage dealt to your team by the TAI Puppet and the Water Puppet. I had the Water Puppet on lockdown most of the time due to Main's sleep attack, but be cautious of his mastery skill if he resists sleep, etc.. It does hurt.) Round One: Use Hinata's mastery skill. Target the TAI Puppet(Green) and wait for the next round.
Round Two: Use Kankuro's mastery skill on TAI Puppet. (The NIN Puppet will attempt to seal Kankuro, ignore this. Your Genjutsu Mirror passive makes this work to your advantage.) Use Main's master skill on TAI Puppet, Water Puppet(Blue), or Earth Puppet(Brown). (Depends really on which Puppet got hit by the Mirror's sealing from NIN Puppet, but I listed them in a Priority for reference: TAI, Water, then Earth.)
Round Three: Use Kimimaro's mastery skill on TAI Puppet. (If you killed the TAI Puppet by the end of round two, then use this on NIN Puppet instead.) Target the NIN Puppet(Yellow) and wait for the next round.
Round Four: Use Kankuro's mastery skill on NIN Puppet. (It could be possible that Hinata may have been defeated by now, since my Hinata was just barely alive by this round but you should be alright still.)
Round Five and Beyond: Use your Main's mastery skill to lock up the Earth Puppet from standard attacking if the skill is available from this point forward while you utilize Kankuro to burn/poison the two down for the remainder of the fight.
Final Notes: Once again, it is possible for sleeps and such to be resisted so utilize your Main's Sealing Jutsu to your convenience really to stop TAI Puppet or Water Puppet from doing some serious damage to your team until you reach the point where you are only fighting the Earth and Water Puppets then use it to freeze the Earth Puppet in it's tracks as you want Kankuro alive to finish his role to DoT them down. Again, hope this Guide helps and good luck!
