The shisui - itachi anbu - iruka/madara/kurenai/masked, paired with MB - SB - BD as mains, is still able to dish out great damage and probably is your best bet. Obviously, don't expect to win every match.

What did you expect, lol?

You came back after an unknown amount of time, meta has shifted heavily in the last months since the release of bonds and madara 5 kage, even more in the last one with the release of naruto sosp... and you expect to come back as f2p and achieve the highest rank in arena? Without a bother?

Are you just randomly trolling or do you actually believe in what are you writing?
