Very nice, I was able to succeed everytime once I figured out what to do.

You can Auto up to Danzo, just try and have WB Asuma's mystery ready for the start of Danzo.

Once you get to Danzo, use WB Asuma and target one of the side groups, but don't use Bee or CF's mystery yet. This should lower their health and keep Danzo's high enough that he casts his Izanagi on them. During round 2, use CF mystery and kill Danzo, easy after that.

For Itachi and Sasuke, everyone kept getting Chaos during round 1. Round 2, use Bee first so he gets Chaos, then use CF, WB Asuma and SS mystery. Itachi should die this turn or the next turn and it's easy after that.
