Description

Daybound and Nightbound are static abilities.

When the game starts, it is neither day nor night. The most common way for this to change is for it to become day as a permanent with daybound appears on the battlefield. This occurs as the permanent enters the battlefield and does not use the stack. Spells and abilities can also explicitly cause it to become day or night.

Once it's day or night, the game will be exactly one of those designations, day or night until the game ends. A game cannot lose its day/night designation entirely, and the designation is the same for all players.

If it's day, transforming double-faced cards with daybound and nightbound enter the battlefield with its daybound face up. If it's night, they enter nightbound face up. Note that transforming double-faced cards have the characteristics of their front (daybound) face while they are spells on the stack, even if it is currently night.

There are two ways for the game's day/night designation to change. If it's day as a turn begins, and the previous turn's active player didn't cast a spell last turn, it becomes night. Similarly, if it's night as a turn begins, if the previous turn's active player cast two or more spells last turn, it becomes day.

As it becomes day, all double-faced cards with nightbound transform to their daybound faces. As it becomes night, all double-faced cards with daybound transform to their nightbound faces. This does not use the stack, and is not a state-based action. Permanents with daybound and nightbound can't transform any other way.

To help players keep track of day and night, a helper card that reminds you of these rules was inserted into packs of Innistrad: Midnight Hunt.
