Rule the Room turned a collection of beloved Commander figures into a bizarrely regal court, with artist Peter Diamond giving each character a dramatic borderless makeover. The drop even rewrote a small piece of Magic lore for the occasion, officially declaring the mysterious Arcanis the Omnipotent a member of the nobility.

Vigilance
Whenever Brimaz attacks, create a 1/1 white Cat Soldier creature token with vigilance that's attacking.
Whenever Brimaz blocks a creature, create a 1/1 white Cat Soldier creature token with vigilance that's blocking that creature.
Deathtouch, haste
When Queen Marchesa enters, you become the monarch.
At the beginning of your upkeep, if an opponent is the monarch, create a 1/1 black Assassin creature token with deathtouch and haste.
Whenever you sacrifice a black creature, you may pay 2 life. If you do, each other player sacrifices a creature of their choice.
Whenever you sacrifice a green creature, you may gain 2 life.
