So I'll be facing my own Daemons next week with the Necrons available to me - pretty poetic huh? Anyway, here are my thoughts. Please bear in mind that I tend not to proxy models if I can help it, and I don't have access to unlimited Ghost Arks! (I have two, which I may include to up the points total of the game, the Daemons can match it).
Here's my list:
Trazyn the Infinite – 175 points
Necron Warriors x 20, Necron Lord w/Resurrection Orb and Phase Shifter, Cryptek w/Tremorstave – 390 points
Necron Warriors x 20, Necron Lord w/Resurrection Orb and Phase Shifter, Cryptek w/Tremorstave – 390 points
Necron Warriors x 20, Necron Lord w/Resurrection Orb and Phase Shifter, Cryptek w/Tremorstave – 390 points
Immortals x 10 (Tesla), Necron Lord w/Resurrection Orb, Cryptek w/Voltaic Staff and Lightning Field – 270 points
Immortals x 10 (Tesla), Necron Lord w/Resurrection Orb, Cryptek w/Voltaic Staff and Ether Crystal – 275 points
Deathmarks x5 – 95 points
Destroyer Lord w/Sepiternal Weave, Warscythe and Resurrection Orb – 170 points
Triarch Praetorians x 5 with Voidblades and Particle Casters = 200 points
C’Tan Shard – Writhing Worldscape and Time’s Arrow – 260 points
Annihilation Barges x 2 – 180 points
Monolith – 200 points
And here's my thinking: -
Trazyn over the Stormlord, because my opponent will be a sitting duck on the first turn, with little firepower of his own, so I certainly don't want Nightfighting rules buggering it up for me. Trazyn, attached to one of the other units, is a good deterrent for the CC daemons, as large units are likely to take big hits from Trazyn's special ability (provided he can kill one member of the attacking squad.)
The Lords with Res Orbs are a no brainer to me. The longer my Crons keep coming back, the better. And they aren't that shabby in CC in terms of surviving long enough to grind out a win against all but the nastiest of CC attackers. They may as well keep the Staff of Light cos the other free upgrades won't do me any good against invulnerable saves.
The Crypteks with Tremorstaves are useful in trying to bog down opposing units, especially when combined with the C'Tan's Writhing Worldscape. I think the Ether Crystal MAY be useful if the Immortals can sit on an objective, and the Lightning Field is at least a deterrent or even leveller in a CC situation. Voltaic Staffs may come in handy to support fire against Soulgrinders.
Tesla for the Immortals - the Inv saves of Daemons means greater numbers of hits will be more effective than AP obviously, and seeing as Gauss Blasters are same Strength, Tesla every time.
Deathmarks may actually be of use against a first turn deep striking army - I'm thinking Target=Fateweaver (let's face it, he's gonna be turning up!)
The Destroyer Lord and Praetorians are a bit of a gamble really, but they might be useful in carving through Plaguebearers and other Nurgle daemons, as they'll be striking at the same time. Also likely to be useful Vs Soulgrinders. Res Orb may help survivability.
The C'Tan shard has the Worldscape to slow CC specialists down (fear the Bloodletters!), and Time's Arrow is specifically for Daemon Prince and Greater Daemon-hunting duty. He'll skulk behind the monolith until he can pounce.
The Annihilation barges should be able to take out big chunks of his infantry, as his retaliatory firepower will be minimal, so two is going to hurt,
The Monolith is nigh on impenetrable to him as long as my C'Tan can intercept big gribblies - I won't let Screamers within 20" of it! But it is most use ploughing towards objectives until it can dump a unit right on top of it. The Flayer arrays and Particle Whip add additional anti infantry firepower.
SO... that's what I have so far, but looking for additional ideas to consider, tweaks etc etc. Points cap is 3K right now, but we could play to 3.5K
Cheers!
