While I appreciate the expansion of success to be 67% versus 50%, I don't like the idea of forcing the King to do anything based on die rolls. A similar game has a similar mechanic that allows a more "Apples to Apples" decision.
However, the die rolls do make it easier for the King to decide. So in this there my be exception. I also appreciate the recollection of ancient myth in your selection of names. Good job!
