I think, it is a strong card. I really love it - and I use it 2-3 times in my FOTR Elven decks.
I'd say that since assigning wounds is a required action, that would happen before the optional action of playing Dismay Our Enemies.
Great! Then it is even better than I thought!
... since the shadow gets to choose the minion so they will choose a minion that's already skirmished.
Yes, but if you kill the minion you has skirmished, the card discards a minion. Incredible! Has anyone any foils of this card left?
