Murders at Karlov Manor Commander

The high throne was empty. At the foot of its dais, upon the lowest step which was broad and deep, there was a stone chair, black and unadorned, for the Steward of Gondor.

Conspiracy: Take the Crown

{T}: Add {C} to your mana pool.
{4}, {T}, Sacrifice Throne of the High City: You become the monarch.

Abilities that trigger whenever you "become the monarch" trigger only if you aren't already the monarch. For example, if you are already the monarch as Custodi Lich enters the battlefield, its last ability won't trigger.

Being the monarch carries two inherent triggered abilities. "At the beginning of the monarch's end step, that player draws a card" and "Whenever a creature deals combat damage to the monarch, its controller becomes the monarch."

If the triggered ability that causes the monarch to draw a card goes on the stack, and a different player becomes the monarch before that ability resolves, the first player will still draw the card.

The game starts with no monarch. Once an effect makes one player the monarch, the game will have exactly one monarch from that point forward.
