Just throw in anything that boost offence. WIth your ninjas, thats Guy, Mifune and Sasuke in p1 for barrier.
All skills that boost damage (lightning etc), tonton as summon.

Eventually you will farm wb from survival and Iruka, which you c*e to phase out Mifune and Guy
Edit:
Also, because without WB you dont have enough chakra in r1 to both barrier and lightning body, just retreat after 3 rounds, instead of entering the 4th round with no skill to cast

R1: Barrier
R2: lightning body/guy
R3: Mifune (might not even want to do this due to animation delay and lack of damage from him not being a lightning ninja), retreat after last ninja hits.
