Wagreb, Innocence Extracted

Each nonland card in your hand without
foretell has foretell. Its foretell cost is equal
to its mana cost reduced by {2}. (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.)
Whenever you foretell a card, Dream Devourer
gets +2/+0 until end of turn.
