If someone has disciples in Fishing Boat, and I discard Darius' Decree to discard the heroes, can A New Covenant heal them? It doesn't specify set-aside areas, and the discard pile is not in play, so would the disciples go straight from set-aside to discard without the chance of being healed?
A New Covenant: "At any time, you may place this card beneath your deck to heal all N.T. Heroes..."
Darius' Decree: "...You may discard this card to discard all Heroes in set-aside areas."
