One ruling from Wizards of the Coast
- 1 June 2011If an artifact you own and a creature an opponent controls go to the graveyard at the same time, you may choose that artifact card as the target of Glissa, the Traitor’s ability (even if they’re the same card: an artifact creature you own that an opponent controlled).
