Samster, Avatar of S.A.M.

When Samster enters the battlefield, send target creature to the SamZone.
Whenever Samser attacks, target opponent
reveals the top five cards of the library. Send all
nonland cards revealed this way to the SamZone,
then opponent puts all cards not sent to the
SamZone this way at the bottom of his or her
library.
