昼形（如果牌手于自己回合中没有施放咒语，则下一个回合成为黑夜。）

- Day and night are designations that the game itself can have. The game starts as neither. Once the game becomes day (or less commonly, night), the game will be exactly one of them—day or night—going back and forth for the rest of the game.
- Before a player untaps their permanents during the untap step, the game checks to see if the day/night designation should change.
- If it is day, and the active player of the previous turn cast no spells during their turn, it becomes night.
