Whenever a legendary creature you control with mana value 4 or greater enters, you become the monarch.
At the beginning of your end step, if you're the monarch, create two 1/1 white Human Soldier creature tokens.
Faramir turns the monarchy into a recurring token engine: become the monarch by playing big legendary creatures (or any other means), then bank two 1/1 Humans every end step while drawing an extra card each turn. You flood the board with bodies, protect the crown with defensive interaction, and grind out advantage until you alpha strike with an anthem or go wide with a finisher.
Built-in card advantage and token generation that snowballs every turn you hold the crown
UW has the format's best protection, removal, and board wipes to defend the monarchy
Tokens synergize with anthems, sacrifice outlets, and convoke/affinity payoffs
Cheap commander (3 MV) that comes down early and rebuilds quickly after wipes
Loses the engine the moment the crown is taken or you're attacked unblocked
Reliant on staying the monarch — fast aggressive tables punish you
Token strategies fold to a single well-timed board wipe if you over-extend
UW lacks ramp and can be slow to close before combo decks go off
