2022-04-29 : "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.'"

2022-04-29 : Any player who has controlled a permanent with a hideaway ability since a card was exiled with it may look at that card.

2022-04-29 : Hideaway now causes you to put the rest of the cards on the bottom of your library in a random order instead of any order.

2022-04-29 : Previously, 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.
