Evoker of the Blind Eternities

Flying, vigilance
Whenever Evoker of the Blind Eternities deals
combat damage to a player, turn X target face-up nonland cards you own in exile face down, where
X is the amount of damage Evoker of the Blind Eternities dealt to that player. They become
foretold. Their foretell cost is their mana cost
reduced by {x}. (On a later turn, you may cast
them for their foretell cost, even if this creature has
left the battlefield.)
