Ninja Exam level 73 Fire Main
Hinata, Guy, and Kiba
Summon: White Snake
Strategy
Round One:
Use Hinata's Mastery skill and target the bottom rows Green Puppet(TAI). Wait for the next round.
Round Two:
Use Kiba's Mastery skill on the Green Puppet(TAI) in the bottom row(behind the Yellow Puppet(NIN). Yellow Puppet(NIN) may try to seal Kiba, but if he is slept from the first round still, should be fine. Kiba should still be able to act before though being in turn 1 position.
Round Three:
Use Main's Mastery skill on the Yellow Puppet(NIN).
Final Notes:
I used a different setup personally, but because it included Iruka, I felt it wouldn't be right to do another guide using him. For the most part however, Guy can fill Iruka's role decently, just doesn't give a shield or bonus to NIN damage. By rights this formation should be able to clear 71-74 no problem. Just tweak positioning so that your main can lockdown one of the Yellow Puppet(NIN) with sleep until you can deal with it.
