You can test at Kakashi NPC which msytery goes off first in Auto. Sometimes it is a little bit confusing, because I was using a team that included Chiyo Chikamatsu of 10 Puppets and her mystery went off first. I tried to use several Ninjas with her for place 1 and found out, that this chiyo isn't that good in my team in auto mode. It wasn't a big deal for me because I usually dont run on auto except I'm forced to do so (Space Time qualification).
