text: If the source of the damage is a permanent, Quest for Pure Flame checks whether you control that permanent at the time that damage is dealt. If the permanent has left the battlefield by then, its last known information is used. If the source of the damage is a spell, whether you control it is obvious. If the source of the damage is a card in some other zone (such as a cycled Jund Sojourners), Quest for Pure Flame checks whether you’re the card’s owner, rather than whether you’re its controller.
