When Hixus, prison warden is destroyed, only the opponant’s creatures are supposed to be enabled. I just had a fight where all creatures were enabled when I destroyed Hixus, prison warden, not just my creatures who had been disabled after dealing damage to my opponant who had cast Hixus, prison warden. I had cast Cast out on two of his creatures but after I destroyed Hixus, prison warden, his creatures began attacking me while I still had 7 shields on Cast Out.
