Hey guys!

Round 1: Wait for all the standard attacks, use Fire Main mystery(if he gets controlled retreat) and make sure that your Chojuro has stacked pos1 equipment so he can get at least 1-2 kills with his standard attacks to gain more attacks

Round 2: Target Tsunade with Madara mystery to interrupt her (most of the other ninjas should be dead from Chojuro's round 1 attacks by now)

Round 3 etc: If only the puppet is alive you can save your mysteries it will die from just standard attacks

Wave 2:

Round 1: Wait for all the standard attacks, use Fire Main mystery, use Madara's mystery on the middle team

Round 2: Most of them should be dead by now so just finish them off
