Switch your main and kurenai positions, and use fire main. Fire main has a debuff reflect, which comes in handy, provides a clone to protect Minato from getting controlled in the first round, the sleep standard has the potential to control an important ninja, and has a nice immunity mystery. Secondly switch out kurenai for anbu itachi. Anbu itachi can clear debuffs on 5k madara, add to the combos, and add more damage.
