Magic Ring is one per deck, though since it's neutral you can put it in each deck.

I love Silver Harp with Mirror of Galadriel -- get your card and keep it too.

3x Galadhrim Healer and 3 Daughters of Nimrodel and 3 Silvan Trackers seems a bit much to me.

Hands upon the Bow works well for Haldir or Legolas to take a just-revealed enemy out in the staging area.

That's as far as my first impressions go.

I tried seven goes at Massing At Osgiliath with modified versions of the two decks, none of which ended well (or lasted past stage 2). I may well be changing to a different plan for deck building.
