The Jester/Usurper

Your goal is to be the one to kill The King. If
you deliver the final hit to The King, you will take their role and become the new King and
go to the Kings starting life total of 50 even if
you have more life. The previous King does
not die, but instead becomes a Jester themselves with a life total of 1.
