Dream Devourer

“Each nonland card in your hand without foretell has foretell. Its foretell cost is equal to its mana cost reduced by 2. <em>(During your turn, you may pay 2 and exile it from your hand face down. Cast it on a later turn for its foretell cost.)</em> <br> Whenever you foretell a card, Dream Devourer gets +2/+0 until end of turn.”
