Im using this team right now. Ssk rinne 1st pos, fire main 2nd with seal mystery and skill reset passive, 3rd shisui and 4th mdr founder.In 2nd round, u can mys 3 times and if u kill someone skill will be reset, im sure with u that the damage pretty good. In arena, this team can rekt nrt 6p in 1 round. Btw, this team maybe not strong like naruto 6p with same bp, cause no immune or leech but still can beat someone stronger, even nrt 6p. The most important always ur 1st pos ini must higher than them.

U can go with itachi anbu and chiriku

Nrt 6p too OP so u will feel like that, i used both of them, except mdr 10 tails, i think both have their interesting, i just dont like nrt 6p everywhere and everyone so base on him, boring and non-tactical fight.
