First things first, when you use a formation make sure to list the units in that formation so that there is less confusion. As it stands your list is actually not legal thanks to the wraiths.
What your using here is the Decurion detachment, which is currently made up of a Reclemation Legion and Living Tomb formations.
Trazyn the Infinite (1) - 130pts
A decent choice, and I'm guessing he's going with the lychguard?
Have you given any thought to Anrakyr instead? He's a little more expensive, but that warscythe makes him even deadlier in combat and would allow you to use fewer lychguard and get some points elsewhere.
Immortals (5) - 85pts Tesla Carabines
Nothing to really say here
Warriors (11) - 143pts
Warriors (11) - 143pts
Don't see much point to the extra warrior in each of these squads, I think your better off staying two squads of ten and banking the points for elsewhere.
Elites: Lychguards (10) - 300pts Hyperphase Sword and Dispersion Shield
A lot of points here, especially when coupled with your warlord likely being here as well. I'd suggest removing two or three.
Tomb Blades (3) - 59pts
2 Tomb Blade: Twin-linked Tesla CarabineShadowloom
1 Tomb Blade: Particle BeamerShadowloom
Nothing much to say here, should do well though you might find the particle beamer not worth it.
Canoptek Wraiths (3) - 136pts
1 Canoptek Wraith: Transdimentional Beamer
2 Canoptek Wraith: Whip Coils
This is what is making your current list illegal, since neither formation you are using allows for wraiths to be brought. That being said, I do have a solution down below.
Monolith (1) - 200pts
Lords of War:
Obelisk (1) - 300pts
Not entirely sure this is the best use of your points. Don't get me wrong, these will both be tough to crack, but your heavily limiting your army in doing so since these two models represent a full third of your points.
I would honestly recommend the following list, which is a Decurion detachment comprised of the reclemation legion, a canoptek harvest, and a judicator battalion.
Now this list gives you a lot of bodies on the table and is very forgiving overall.
It also has the ability to swap out the auxiliary choices for other ones, such as the Annihlation Nexus, Destroyer Cult, and Deathbringer flight. (Well swap out the Judicator Battalion for any of those three, since each one is +300 points.)
