As Primal Clay enters, it becomes your choice of a 3/3 artifact creature, a 2/2 artifact creature with flying, or a 1/6 Wall artifact creature with defender in addition to its other types. (A creature with defender can't attack.)
When you play Primal Clay, choose one—Primal Clay is a 2/2 artifact creature with flying; or Primal Clay is a 3/3 artifact creature; or Primal Clay is a 1/6 artifact creature that counts as a Wall.
