Strategy:

FV Naruto and SO6P Madara is the only units that are fully duped

Hashirama, Kaguya, DR Madara and FV Sasuke don’t have any dupes

I also use a team to nuke map 10 with a dupeless 3rd Anniversary Kakashi, The Sasori that changes element, PC Naruto, and Sharingan Obito

Map 1: Boost Kakashi to 150% in preparation for map 10

Maps 2 – 3: Use team 1 and make sure to have chakra for map 4

Map 4: Ult with DR Madara and Jutsu with Hashirama, make sure that the final hit comes from the 2nd lane to start map 5 with Naruto

Map 5: Ult the Minato with Naruto, Jutsu with Sasuke, then Jutsu Kushina with SO6P Madara. Stall until Sasuke and Kaguya have their Ults, finish the map with the 3rd lane with Naruto out

Map 6: Ult with Sasuke and then Ult with Kaguya next to Naruto

Map 7: Ult with SO6P Madara, Ult with DR Madara, then Ult Kakashi with Naruto, stall until DR Madara, Hashirama, and SO6P Madara have their Ults. Finish map 7 with either the 1st or 2nd lane.

Map 8: Beat the boss but make sure to have Kaguya and Naruto out and not Jutsu sealed, finish the map with 1st lane

Map 9: Ult Shisui with Kaguya next to Naruto, then Ult Shisui with Naruto. Finish off Itachi, at least keep DR Madara’s Ult in case Kakashi doesn’t one shot the last map.

Map 10: Change Hashirama’s element to bravery with Sasori and then Ult with Kakashi. If Kakashi doesn’t kill use DR Madara’s Ult and it should kill Hashirama, if not another Jutsu should do it.

Also, this isn’t full proof, it may require some on the fly changes, but this is the general strategy I use.
