4 rulings from Wizards of the Coast
- 29 April 2022 Any player who has controlled a permanent with a hideaway ability since a card was exiled with it may look at that card.
- 29 April 2022Hideaway now causes you to put the rest of the cards on the bottom of your library in a random order instead of any order.
- 29 April 2022"Hideaway N" means "When this permanent enters the battlefield, look at the top N cards of your library. Exile one of them face down and put the rest on the bottom of your library in a random order. The exiled card gains 'The player who controls the permanent that exiled this card may look at this card in the exile zone.'"
- 29 April 2022Previously, permanents with hideaway entered the battlefield tapped. This ability has been removed from the definition of hideaway. Older cards have received errata to have an additional paragraph that reads "[This permanent] enters the battlefield tapped," and they now have hideaway 4.
