I say, you can not start with
Elrohir,
Elladan, and
Gandalf, LoM.
And I do not understand why you play
greatheart. Would not be
Greatest of the mearas better? Though I understand the exert-wound step.
About Gandalf Deck: look for Gandalf Ring-Bearer decks in the forum. They work well with forest Nazgul, as they are cheap, so you can reconcile a lot cards, especially important to get
cards for
BoO.
For reconciling, I forgot above:
Secluded Homestead!!!!! Forests
EDIT: haha, I just noticed, that Gandalfs Abrevation is BOO
