One ruling from Wizards of the Coast
- 1 December 2004The enchanted permanent must be both an artifact and a creature. Domineer can be cast only on an artifact creature. Domineer “falls off” and is put into the graveyard if the artifact creature it’s enchanting stops being an artifact or stops being a creature.
