Also, you usually have good feedback Sasori. Dunno if you were pressed for time, but adding in what -is- good vs. Tyranids (and why) as far as a dicussion might be more helpful, rather than just kinda commenting on how poor my choices were.
I've been a lot busier lately, so I do apologize for the quick respose, was kind of a on my way out kind of thing.
Anyway, on the the meat and potatoes.
HQ
Nemesor
Royal Court: 5 Crypteks of Destruction, 1 Lord with Resurrection Orb
Troops
6 x 5 warriors
Fast Attack
4 destroyers, 3 heavy
6 Wraiths 5 whip coils, 1 pistol
10 Scarabs
Heavy Support
3 Spyders
3 Spyders
Total: 1750
This reads a lot like a 5th edition list, (Like the massed Lanceteks) so, as with any change we will need to adapt to it. I'll go piece by piece on what I think.
Nemesor
I'm honestly not a fan of him. You're paying a lot of points, for a tactically flexiable character, but with somewhat limited use. He's not a bad character per say, but I prefer to take a Vanilla Overlord most of the time.
Royal Court: 5 Crypteks of Destruction, 1 Lord with Resurrection Orb
With the fundemental changes in 6th, we really don't need to spam these guys anymore. You could probably take 1 for a Solar pulse in a
TAC and be pretty set. You may consider swapping these guys out for other Court Options, or just using the points elsewhere.
Troops
6 x 5 warriors
With the New emphasis on objectives, this is proably a poor choice. You want to either buff these guys up by combining a few squads, Start taking Immortals, or a combination of both. They are both Solid options, but you have to practice care with the big blobs, and your Lords getting sniped out now. I honestly prefer taking Immortals now as my troops. With the changes to Gauss, any way you outfit your troops, they should be shredding the smaller bugs before they can get close to you.
4 destroyers, 3 heavy
You'd probably want to bump the squad up to 5, and drop a heavy. Two is plenty, most of the time, for both Anti-tank, and Anti-infantry. A pretty strong choice, now.
6 Wraiths 5 whip coils, 1 pistol
Wraiths are always a great choice. I'd personally consider dropping the pistol though, since wound allocation has changed. Getting more Wraiths is never a bad thing, I think another squad could serve you well.
10 Scarabs
I'm really not feeling these guys anymore. With the advent of hullpoints, I just feel they are not really needed anymore. I'd really put these points to use elsewhere.
Heavy Support
3 Spyders
3 Spyders
Spyders are a great value
MC, but I honestly think with scarabs not being as useful anymore, these guys take a bit of a hit. They aren't a bad choice by any means, but I feel that there are better options in a more optimized list.
You have a few routes you can go. You can go all out flyers, and Tesla him to death. From that list, his Army really has nothing that can deal with flyers. They'll just zoom around and blast him to death. However, there are other routes you can go.
Typically, what he does is he deploys the 2 tervigons, swarmlord, the trygon, and gargoyles. The trygon and the swarmlord move up together (trygon in front, protecting the swarm lord), and the tervigons stay behind and spawn termagaunts to hold objectives. He's very good at protecting his Swarmlord, so he hides his guys so that I don't have line of sight with him with...anything. By the time it's turn 2, he usually gets most or all of his deep striking units in. Then, I spend the rest of the game trying to hold this off, so it always ends up that he either takes my objectives, or he contests them. In either case, he wins the game because he still has his termagaunts on his deployment zone holding his objectives.
If he is using the Trygon to protect the Swarmlord, that means he's going at a much slower speed. Use that to your advantage. The Trygon should be your number 1 Priority, along with the Gargoyles. The fact that he's not using Tyrant guard also gives you a powerful advantage against the Swarmlord. Honestly, depending on how you build your list, you can put enough firepower to smoke that Trygon in single turn, without problem. The Swarmlord will probably take about 3-4 turns to get into combat with you, so I'd worry about him later. Whatever you do, don't send Wraiths against the Swarmlord, as he will obliterate them.
Heres a quick list I came up, while not a perfect
TAC, I think it'd do fairly well. I did not include any flyers in it.
1750 Pts -
1 Overlord Warscythe; Mindshackle Scarabs; Sempiternal Weave; Phase Shifter;
1 Destroyer Lord, Warscythe; Sempiternal Weave; Mindshackle Scarabs
9 Immortals,
8 Immortals,
8 Immortals,
5 Destroyers Heavy Gauss Cannon x2
5 Destroyers, Heavy Gauss Cannon x2;
6 Canoptek Wraiths,; Whip Coil x3;
1 Annihilation Barge
1 Annihilation Barge
1 Annihilation Barge
This was just a quick list, not super optimized, so it can be tinkered really easy to suit your needs. There is no court, so no real need for an Overlord, you can easily swamp him out for another
Dlord, replace Destroyers with more Wraiths, etc etc.
As for a gameplan, I'd focus on Knocking out his Trygon first. That thing will just play with your army, if you don't take care of it. Rolling average, you should have enough firepower to take care of it in a single turn. The Wraiths and
Dlord are excellent at killing Tervigons, and can move about quickly, earning you a large advantage in mobility.
Use the Destroyers to blast at his big bugs first, then his smaller bugs. You'll average pretty close to the same amount of wounds with the 3 destroyers, to the one heavy on T6 3+ saves, but it also allows you volume of fire in the cases of taking care of the smaller bugs, and Zoanthropes.
The Overlord can be whatever you need him to be. He can be swapped out, or he can be a roadblock for a big bug. Even the Swarmlord would think twice about taking on something with
MSS, as that gives him pretty good chance to kill himself.
Hope this helps!
