Have you considered using
Restless Maiden with
multiple copies of
Dernhelm's Blade? It's a very nasty combo in a deck that features
Swordthain, since you can play the blade on Eowyn to wound, discard it with her text, then play it and wound AGAIN with
Swordthain.
At worst, you sometimes get lucky with two (or more!) copies of
Dernhelm's Blade in your hand and you can play one, discard, then play the other for the same effect.
Just a thought. Not sure if you can fit it in, but it wouldn't be a terrible idea. I have a whole deck built around that combo.
