The way i did it, i made sure gaara had the lowest hp of all my ninjas, (yes even if you take ur life magatamas), then with kazekage gaara i used sage naruto and yagura(as soon as you have c*ra copy sage hashirama) with wind main, also i made sure i waited for sage hashirama to do his mystery on gaara, the AI will always attack your lowest life ninja if you dont do any mystery(that's how it worked for me), then with sage naruto i target naruto kurama and stop his mystery, from there hoped my sage hashirama copy crowd control madara and sasuke while i killed naruto kurama, on 4th round either madara or sasuke needs to be dead. so you can focus sage hashirama and another of your choice(i prefer sasuke or naruto kurama).

talents are 3-4-4-3-4 with the yellow shark.
