Play in any opponent’s zone, under his control. Forced: At the beginning of your turn, you must sacrifice a non-development, non-quest card in this zone, if able. Action: At the beginning of your battlefield phase, skip the rest of your battlefield phase to destroy this card if a unit is questing here.
Can the non-development, non-quest card be the card that is attached to the Heroic Task? It is not considered to be out of play. Also can you sacrifice cards that have been attached facedown as experience?
