2022-10-14 : In a multiplayer game, if the owner of In the Trenches leaves the game, the exiled card will return to the battlefield.

2022-10-14 : The activated ability can only be activated once per game. If the ability is countered or otherwise fails to resolve after being activated, it can't be activated again.
