Well, with those lots of exerting (inlcuding Gron himself), I don't think another
Hard Choice would hurt, even though you have 4 copies of Gorn...
But I think the Freeps is a great Deck as it stands. Making
Deep in Thought work maybe isn't that easy, but if you can.. nice

consider
Brooding on Tomorrow, maybe. Otherwise, I always found
Asfaloth, Elven Steed a great card to add in such a Deck.
But I'm just asking why still people are playing
Ulaire Attea, The Easterling and
Ulaire Otsea, RiT!? those cards aren't really that good, consider that wounding an ally doesn't make that an issue mostly and making able to win
Ulaire Otsea, RiT a skirmish is sometimes as hard as convincing Georg W. Bush of Democracy, in fact you aren't even using
Blade Tip.
Even though you rely on Return to it's Master, one or two
The Witch-King, LotN won't hurt. As wil not
Ulaire Nelya, RiT, which is a great card that can easily avoid an early dead comp. And it also replaces
Ulaire Otsea, RiT. Nelya costs one mroe, but is much stronger in exchange. And if you care about high costs, I assume
Morgul Gates being a nice card.

Your Combo might die to hand clog, but if it works...

Oh, and if you aren't using
Aragorn's Bow,
Flame of the West is obviously a much better choice in that Deck, not only cus' of the extra vitality provided. As Swarm Protection,
Mithrandir, Mithrandir! might be an option, or the
Aragorn's Bow mentioned above. And Corsairs always cause trouble...

@Door orc: Yes it is, and a very good choice for this Shadow side.
