Dumah, Angel of Dreams

When you cast Dumah exile the top X cards of your library. You may cast a permanent from among them without paying its mana cost. Put
the rest of the exiled cards onto the bottom of your library in a random order.
I looked into the sky and saw a truth written in quiet motion.The turning wheel rises and as it falls it shows
us what we've seen a vision from beyond, no different than a vision from within.
