I don't think that Deck will work. My cousin actually playes a
Mithrandir Deck which runs 4x
King in Exile, but starts
Faramir, Captain of Gondor with
Vorondil, and Nrya,
Gandalf's Staff etc. just a basic Gondor beatdown with
Mithrandir and some tools. It works pretty well, cus' it's simple, I wouldn't try to go too many ways. The Decklist above is just too big, you're trying to do many things at the same time, and you usually get crushed by good shadow sites really easily.
And 39 (!) cards onyl work if you're able to draw about 6 or more cards during reconcycle. You will clog your hand with many events. If you discard them with Lego, you also could have included someting better. I only see hope if you pair this Deck with Moria. Maybe I'll post my cousin's Deck one day when I'm in Prague again.
