• "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
• 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 4.2022-04-29
• 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
• At the time the ability resolves, you'll get to play the card if you declared three different creatures as attackers at any point in the turn. A creature declared as an attacker in two different attack phases counts only once. A creature that entered attacking (such as a token created by Militia's Pride) doesn't count because you never attacked with it.2007-10-01
