The Seer Groa

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 cast a Spell from Exile, draw a
card.
The cosmos lay bare to me.
