Permalink

There are two inherent triggered abilities associated with being the monarch. These triggered abilities have no source and are controlled by the player who was the monarch at the time the abilities triggered. This is an exception to rule 113.8. The full texts of these abilities are “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.”
