Prophecy 1 (At the beginning of your upkeep,
exile the top card of your library face down and draw
a card)
{u}{t}, choose a card type and reveal an exiled card
by Nox. If the card shares a type with the chosen
type, you may cast it without paying its mana cost. Otherwise, put it into your hand and you lose life
equal to its converted mana cost.
