, Sacrifice Mirror of Fate: Choose up to seven face-up exiled cards you own. Exile all the cards from your library, then put the chosen cards on top of your library.
10/1/2009 You don’t choose the exiled cards until Mirror of Fate’s ability resolves. It doesn’t matter how they wound up in the exile zone.
10/1/2009 Exiled cards are face up by default; they’re face down only if the effect that exiled them said so. For example, the cards from your library that Mirror of Fate exiles are exiled face up.
10/1/2009 You choose the order that the chosen cards are put on top of your library. You don’t have to show anyone else that order.
