Three headed oracle

At the beginning of your upkeep, look at the top three cards of your library. At random exile one face down, put one at random into your hand, and put
the rest into your graveyard.
You may play the exiled card for as long as it remains exiled, and you may cast it for {w}{u}{b} instead of its original casting cost.

"The past, present, and future whisper their secrets to its three heads—if you dare to listen."
