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 cast Primal Clay, you must choose whether to make it a 1/6 wall, a 3/3 creature, or a 2/2 flying creature. Primal Clay then remains in this form until altered by another card or removed from play.
