I got a request to post this deck, which gives me an opportunity to muse like an old man. I celebrated my birthday last week so it seems fitting. This isn't the best deck in Fellowship Block, nor is it the best build of this deck, but it illustrates something about tournaments. Why do I start 
FotS? Why is the Nazgul support mix so varied? Read on.

Blade Tip*** Why start 
Fots?
Because it's a lot harder to lose to yourself. As old-timers will remember, real life tournaments didn't act like GEMP. To reach the Top 2 in a Territorial, you had to go 6-0 or 5-1 with good tiebreaks, in a tiebreaker system that punished early defeats much more harshly than losses later. There were also many mediocre decks, inferior due to strange ideas or card unavailability. The point of this build was to be strong against mediocre decks, get to 2-0 or 3-0, and then try to win 50/50 matchups. The 
FotS version that starts Gimli and 
Legolas Greenleaf has more upside because you can play stuff on Gimli immediately, and 
FotS jumps in at base strength 9. But that requires grabbing him. Doing a quick probability calculation, having 6 ways to get Gandalf (2 + 4 
AWINL) in a 68 card deck, plus a mulligan, gives you roughly a 80% chance of having the opening Gandalf. If I want to reach a Top 8 at 5-2, that's fine, as I can not find anybody and take a Round 2 loss to something like Hobbit Hospital / cheap Moria. But to go 5-0 and win a local event, it's not.
Similarly, there are 3 
Glamdring for stability. Gandalf fights! A lot! Aragorn has 3 weapons because he fights! A lot! Boromir is an extra man to hold Gondor stuff, while a higher variance deck would run something else like 
Ottar. There's no 
Aragorn's Bow to avoid double 
Relentless Charge; 
Aragorn RotN reduces the chance of stupid swarm; Nelya site-changer lets me swap site 1 to the Pony going second, instead of the potentially Damage +1 twilight version. All but one of the Nazgul have 3 vitality; there's no Lemenya because Lemenya is a "win more" card. If the Fellowship is so weak that it can't kill a 9/2, I'm already winning.
*** Why is the Nazgul support mix so varied?
Because I don't know the meta. If you have the right support, Nazgul are a Tier 1 deck. If not, you have 4-6 dead cards, and a Tier 2 option (or less). For instance, packing 4 
Relentless Charge is great if someone runs archery, but not dwarves. Against dwarves I want 4 
Morgul Gates. To run 
Their Power is in Terror requires dropping something else.
I always recommend 
All Blades Perish and 
Frozen by Fear. They always work - Frozen gets plenty of unexpected wins, and 
ABP stops 
PATHS, directed archery, and a fully extended opponent. Beyond that, you have to choose. I've tried pretty much everything, even dropping the 
Black Breath and 
Blade Tip for lots of maneuver wounding in the "I hate Elf ally archery" variant. There's always a right answer, but I have to know the right question. 
Honestly, I did most of my Fellowship Block play before the release of Realms of the Elf-Lords and not much over that summer/fall. Aided substantially by 
Aragorn Heir to the White City and the ridiculously under-costed 
Gondor Bowmen, this is not the best deck on either side. I have a 70% win rate on Gemp, which feels about right.
