So, your deck might be a little on the big side, shadow-wise, since you pack a lot of FP events and your hand might get clogged. I'd keep
Stricken Dumb, it's a great way to fight off tanked-up companions, and since you WANT as much twilight as you can get, I'd cut off 1 Enquea, 2 is plenty for crowd control. Also, if you're gonna play with Nazgul Swords, you might consider
Drawn to its Power and upping Toldea, great crowd-control technique. On the FP Side, I'd play a second
Bounder. This way, you can dodge opposing Tower Assassins and losing him at site 7 if you draw the second one late enough. You might consider fitting in
Wreathed in Shadow into the Shadow side for a little more protection, and some
Fireworks on the FP side for recycling (you can reduce the deck a little, cutting some copies of some events). Last, but not least, if the idea of your Shadow side is slowing down the opponent so you can outrun them, consider switching to Twilight Nagzul, they tend to be a lot scarier, are easier to defend, more flexible and, save for Sam (which would mean playing SOME copies of
Helpless), burdens REALLY add up in Fellowship Block. Oh, and I'm not sure I get the second copy of Gandalf. Healing, maybe? I'd eschew it and pack
Greenleaf in its place. Also, you might want to rethink playing 3 much-needed strength-pumping conditions alongside
Sleep, Caradhras. Elrond might be a nice addition as well, helping slim down the deck.
