Official rulings

The 8 most recent official rulings for Derelict Attic // Widow's Walk, newest first.

• 2024-09-20 An ability that triggers "whenever you fully unlock a Room" triggers when a door becomes unlocked and the other door of that Room is already unlocked, or when both doors of that Room become unlocked simultaneously.
• 2024-09-20 If a Room enters from any zone other than the stack, it will enter with both halves locked.
• 2024-09-20 While on the battlefield, a Room's characteristics are a combination of the characteristics of its unlocked doors. For example, if Bottomless Pool // Locker Room is on the battlefield with both doors unlocked, its names are Bottomless Pool and Locker Room, its mana value is 6, it's a Room Enchantment, and it has the abilities in each door's text box.
• 2024-09-20 To cast a Room spell, choose a half (or "door") to cast. There's no way to cast both halves of a Room card. When the Room spell resolves, the corresponding door becomes unlocked as the Room enters.
• 2024-09-20 Each Room card has two names. If an effect instructs you to choose a card name, you may choose one of those names, but not both.
• 2024-09-20 Some doors have abilities that trigger whenever you unlock that door and require one or more targets. You can unlock that door even if there would be insufficient legal targets for that triggered ability. The triggered ability won't go on the stack.
• 2024-09-20 A creature attacks alone if it's the only creature declared as an attacker during the declare attackers step (including creatures controlled by your teammates, if applicable). For example, the ability granted by Widow's Walk won't trigger if you attack with multiple creatures and all but one of them are removed from combat. Similarly, creatures that enter attacking later in combat won't be considered when determining whether or not a creature attacked alone.
• 2024-09-20 While in any zone other than the stack or the battlefield, a Room card's characteristics are a combination of its two doors. For example, Bottomless Pool // Locker Room has a mana value of 6 while it's in your library. If an effect allows you to search your library for a card with mana value 4 or less, you can't find Bottomless Pool // Locker Room.
