Free Mason

You make all decisions when a player surveils. (Other players' cards are revealed to you.)
When Free Mason enters the battlefield, each player surveils 2. Then, manifest the top card of target player's library.(Put it onto the battlefield face down as a 2/2 creature. Turn it face up any time for its mana cost if it's a creature card.)
Whenever there are no facedown cards on the battlefield, transform Free Mason.
