Have you consider to use some
Unheeded for extra killing power?
If you have a problem with threats maybe a couple of
Nine-fingered Frodo and the Ring of Doom or
Hearts Raised can help you out. I think the first option is better considering that a exert on your hobbits isn´t that much
I think that
Windfola isn´t a good horse for Eowyn. I would say that
Brego is far more useful since he heal when played, cost less twilight, don´t have to exert twice (which is no good for
LoI) and your opponent will probable not discard it cause if he/she does you can discard Merry and get him back healing Eowyn again!
If you have room maybe add a couple of
Strength of Spirit cause you can use it to wound more with Eowyn, discard more conditions with
Firefoot or just prevent some aimed exertion...
