如果当前既非白昼也非黑夜，则于偏执星象家进战场时成为白昼。
每当白昼成为黑夜或黑夜成为白昼时，弃至多两张牌，然后抓等量的牌。

- You may choose to discard no cards when the Obsessive Astronomer's triggered ability resolves.
- If a triggered ability triggers whenever day becomes night or night becomes day, it only triggers if it was already either day/night and becomes the other. It does not trigger when the game becomes day or night for the first time.
- 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.
