Glimpse the Blind Eternity

Starting from the first card of your library
separate your library into three piles facedown.
An opponent picks one of those piles, that
pile becomes your library. Pick one of the two
remaining piles and add it to your hand, Exile
the last pile face up and take damage equal to
the amount of cards in your exile. You get an
emblem that says: "Your mana pool does not
empty as phases or turns end."
