Ok, like I said, I played an Enduring beatdown deck that I LOVED, and I've gotta say, 4x
Black Captain and 4x
Fell Beast are key. That's the type of thing that's really going to wreck your opponent, especially when you draw a
Between Nazgul and Prey (I'd suggest adding another 1-2 of those, for sure).
As far as wound prevention goes, yes, it's important. The idea is that you're going to be injuring your own guys, so you need a little something to make sure the Free Peoples player doesn't finish the job. I ran
All Blades Perish in my deck -- two copies, I believe. A single copy of
Wreathed in Shadow isn't a bad idea, either.
Ulaire Attea, Keeper of Dol Guldur is always a good choice for beatdown, even if he's not Enduring. He's just way too good.
Ulaire Toldea, Thrall of the One is probably going to be your second-best Enduring Nazgul (after the Witch-king). Assigning him with
BNaP and then healing him twice for damage +2 is enough to kill most companions.
I don't think that
Enquea, ToTO is really necessary in this deck. Yeah, he gets bigger with exertions, but not as big as a Witch-king, and he doesn't get the damage +1 of Toldea. I'd consider going with Lieutenant of Morgul instead, just for the sake of taking out big fellowships.
I remember in my deck I had a few copies of
Black Dart, but that was just because Rohan was pretty heavy and Eomer could often keep from being overwhelmed if he had a mount. After all, if both the companion and the minion get strength +2 for each wound on the minion, the companion is coming out ahead in terms of overwhelm possibility. Unless you see yourself fighting a ton of Rohan, I wouldn't worry about the Black Darts.
I actually found an old decklist that's very close to what I used in my state's TOC in 2004, but it's not quite the same; there are definitely a few things I remember being my deck that aren't showing up in this list, though I'm not sure what was taken out/added/whatever. For starters, the list shows that I only have two
Between Nazgul and Prey -- maybe I only owned that many, but always wanted more, 'cause it's so good. =P
One thing I noticed from my list is that I had a ton of stuff for the Witch-king -- 4 Witch-kings, 4 Fell Beasts, 2 Pale Blades and a
Black Flail. I know it seems kinda combo-intensive, but if you get a mounted, armed Witch-king, there's a good chance two companions are dying. And Fell Beasts allow you to cycle his weapons out if you're getting jammed up and can't draw a copy of him. I love
Fell Beast in pretty much ANY Nazgul deck. It's just a perfect card.
