RULINGS

• 2021-09-24 Permanents with daybound and nightbound can't transform via any means other than their daybound and nightbound abilities. Notably, older cards such as Moonmist that instruct a player to transform permanents don't affect permanents with daybound or nightbound.
• 2021-09-24 If it is night, and the active player of the previous turn cast two or more spells during their turn, it becomes day.
• 2021-09-24 After Arlinn, the Moon Fury's second loyalty ability resolves, she is a Werewolf creature and not a planeswalker, so she doesn't lose loyalty counters when she's dealt damage.
• 2021-09-24 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.
• 2021-09-24 Before a player untaps their permanents during the untap step, the game checks to see if the day/night designation should change.
• 2021-09-24 Arlinn, the Moon's Fury's first loyalty ability is not a mana ability. It uses the stack and may be responded to.
• 2021-09-24 If Arlinn, the Moon Fury's second loyalty ability is making her a Werewolf creature and it somehow becomes day, Arlinn will transform, but the effect making her a Werewolf creature will continue to apply for the rest of the turn.
• 2021-09-24 For more information about Day and Night and the Daybound and Nightbound abilities, please see the Innistrad: Midnight Hunt Mechanics atricle (https://magic.wizards.com/en/articles/archive/feature/innistrad-midnight-hunt-mechanics-2021-09-02).
• 2021-09-24 If you cast a spell with daybound during night, that spell will be front face up (that is, daybound face up) on the stack. However, it will enter the battlefield with its back face up (that is, with its nightbound face up). It won't enter with its daybound face up and then transform.
• 2021-09-24 If it is day, and the active player of the previous turn cast no spells during their turn, it becomes night.
• 2021-09-24 If it is night, permanents with daybound that enter the battlefield without being cast will enter with their nightbound faces up.
• 2021-09-24 If it's neither day nor night, and a creature with daybound and a creature with nightbound somehow appear on the battlefield at the same time, it becomes day. The creature with nightbound will transform.
• 2021-09-24 Double-faced permanents with daybound transform to their nightbound faces as it becomes night. Similarly, double-faced permanents with nightbound transform to their daybound faces as it becomes day. This happens immediately and is not a state-based action. It happens any time it becomes day or night, not just during the untap step.
