Kingdoms EDH is a variant that uses secret roles and one revealed one, decided by a simple shuffle and deal of all five basic lands, plus a second Mountain if you have six players. Here are the roles:
Plains The Monarch: Be the last player standing. The knight making it to the end is optional.
Forest The Knight: Be last with the monarch, in which case the knight reveals their role and the game ends.
Mountain The Bandit(s): If the monarch dies, the bandits instantly win the game.
Swamp The Assassin: Be the last player standing. No need to have dealt the final blows.
Island The Usurper: If Usurper deals the kill shot to the monarch, they swap roles with new life totals.
One key change is the Monarch as the only public role starts with 50 life instead of 40, and goes first. It is best for experienced players that can pilot their deck well and adapt their strategies.
