The idea around this deck is to get as many readying effects on Eowyn as you can, and either use her as a questor/attacker or a questor/defender. Since she can only have 2 restricted attachments, that's the deal.
In this deck, Eleanor becomes a pretty stable defender once Gondorian Shield is on her, and you can use the various horses and Spear of the Mark to make Dunhere pretty cool.
Snowmane is for Eowyn, but anything you can do to get her 2 actions a turn is great. I had her quest successfully and then use her ability to hit for 14 with Herugrim on her, and I thought that was pretty cool. My other favorite thing I did was to trigger her ability with Grappling Hook to battle quest for 10.
Some issues I have had with the deck are mostly about resources, since the deck is Spirit-heavy, to be sure, but hopefully you draw a Song quickly.
Favorite card in deck: A surprise Tireless Hunters--great to bring some beefy dude over and have Eowyn defend with Golden Shield safely since the Shadow card is gone. Or Eleanor to defend and Eowyn delivers a big-ole beat down.
