Stalks of Flax: "On activation, discard this card to exchange two O.T. human Heroes in your territory with two Heroes in an opponent's territory for two turns."
Play-as: "Discard this card to exchange 2 O.T. human Heroes in territory with 2 Heroes in an opponent's territory for 2 turns."
If the heroes exchanged with an opponent's heroes are removed from play by discard or capture before the exchange duration ends, do the remaining heroes not swap places again? Or more simply, if I discard the heroes I exchange to, what happens to my two original heroes?
Thanks for the clarification!
