Hey guys!

Round 1: Wait for some standard attacks and use Kushina's mystery on Hiruzen, use Fire Main's mystery and Madara's mystery also on Hiruzen

Round 2: Wait for some mysteries and standards, then use Kushina/Madara on the middle team and try to time your Itachi's mystery when Hiruzen revives

Round 3: from now on it should be easy, just finish
