If I use Stalks to exchange for opponent's heroes and then put them in Goshen or Kerith Ravine, after 2 turns do they just return to the opponent?
Stalks - "On activation, discard this card to exchange two OT human heroes in your territory with two heroes in an opponent's territory for two turns."
Goshen - "Protect contents from all effects. If your Genesis or Exodus Hero has toughness */0 or less, you may place it here instead of discarding it."
Kerith Ravine - "Set this Fortress aside. Holder may put one O.T. human Hero in this Site to protect it from harm. Set-aside enhancements work in this Fortress."
Similarly, if I use Stalks and then set one of those Heroes aside with something like Witnesses to Creation, would it switch over to the opponent's set-aside area, and would he be able to bring the Hero back before the seven turns are up?
