Banished Seer

Slip (At the end of any phase, if this creature is tapped, exile it. Return it to the battlefield under owner's control at the start of your next turn)
When Banished Seer dies, you may take all cards one player owns in exile and put them on the bottom of that player's library in a random order.
"I do not see what will be. I see what was, and is coming back."
