Pathless Country and Tireless Hunters.
I think that the "enemy attacks" step has already begun at this point, so the whole thing doesn't work to begin with.
Nathan, that was my take as well. I think Tireless hunters was meant to be played after Shadow cards are dealt, but before the enemies actually start attacking.
Can anyone second this?
Yeah definitely Tireless Hunters can't be played once you begin to resolve enemy attacks.
If you did drag the enemy away however, say with Quick Strike + Aragorn (Tactics) taking down a different enemy, the shadow effect should still resolve.
In that scenario, you would start resolving the original attack, then reveal the Pathless Country shadow card. Then, another player would do Quick Strike + Aragorn and defeat some other enemy, and drag the original enemy over to him. The original attack would finish resolving (against the original player, even though it is no longer engaged with that player). Then, the shadow effect does its thing: the enemy will go to the next player (presumably the "next player" in relation to the original player who revealed the shadow effect, and attack. Moving the enemy around won't prevent the attack.
