So I'm making a jank oathbreaker deck with Karn, the Great Creator and his second ability cares about the exiled card bein face up. So if I put my 5 cards into exile face down and then Mangara's Tome leaves the battlefield They would stay in exile. But are they considered face up now? I feel like the oracle of the original card suggests that. But the new errata just doesn't mention what happens, when it leaves the battlefield, since the cards are already in exile. The new errata sounds like the cards would remain face down wich would be disappointing.
Card tags are mandatory when asking questions in the Magic Rulings forum. Please check your private messages to learn how to use them. I’ve added them for this post. -MadMage
Nothing about the Tome, or the rules of the game, says that face-down cards in exile are turned face up just because the source of the effect that exiled them is gone. They will remain face-down and Karn cannot grab them from Exile.
