So, to chime in on this thread- after checking out the mythic paths a little more carefully, I'm pretty happy with the idea of Morevek going Trickster. I originally grabbed the Stolen Fury trait (aligned with Champion), which was never a particularly great option for a low-Str magus who is not building toward combat maneuvers. While ignoring DR on a particular target is not bad, being able to take 20 on an acrobatics check to tumble behind someone and flank would be pretty sweet every now and then.

I don't know who currently has the Trickster trait, but it's worth having the conversation about what might suit that person better? :D
