6/15/2010 : The four permanents are put on top of their owners' libraries in sequence. That means that a single artifact creature, for example, can't be chosen as both the creature and as the artifact.
6/15/2010 : If there are no applicable choices for one of the permanent types, it's simply skipped. The process is still repeated for the other listed permanent types.
6/15/2010 : If a player owns multiple permanents chosen this way, that player shuffles his or her library just once.
6/15/2010 : The owner of a token permanent chosen this way still shuffles his or her library, even though the token ceases to exist.
6/15/2010 : If one of the chosen permanents is controlled by an opponent but owned by you, you'll wind up shuffling your library.
