Chihaya Mifune

Whenever you cast a spell from exile, draw a card, then discard a card.

{g/u}{u/r}: Foretell the top card of your library. Its foretell cost is the same as its mana cost
reduced by {2}. If you would foretell a land
card this way, instead put it into your graveyard. (You may look at the foretold cards.)
