Mental Ascension

When Mental Ascension enters the battlefield,
scry 3, then exile the top three cards of your
library until it leaves the battlefield. You may
play those cards as if they were in your hand.
Skip your draw step.
At the beginning of your upkeep, you may put a
card exiled with Mental Ascension to its owner's
graveyard. Then, if there are no cards in exile
exiled with Mental Ascension, sacrifice it.
