The Ruler

Starts with a bonus 25% life (e.g 50 in EDH).
The Ruler's goal is to be the last person standing,
removing other players through conventional
means for a game of Magic to the appropriate
format ('21 commander damage' rule applies in
EDH Kingdoms). The Ruler is the only player
who reveals their role card from the start, which
they must do before the first round of play.
