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.
