So, I'm playing a game of multiplayer and my opponent plays banisher priest and removes one of my creatures. I can't kill it, but instead I kill the player, will my creature come back (assuming the game does not end)? I know with oblivion ring it will not, but this returns it without a trigger, so I wasn't sure.
It will come back. That was one of the two reasons Wizards stopped printing cards like those with triggered abilities. (the other reason is that you can sometimes ignore the return trigger completely)
