731. Day and Night

Rules in this chapter

• 731.1 Day and Night Day and night are designations that the game itself can have. The game starts with neither designation. “It becomes day” and “it becomes night” refer to the game gaining the day…
• 731.2 Day and Night As the second part of the untap step, the game checks the previous turn to see if the game’s day/night designation should change. See rule 502, “Untap Step.”
