New necron list

So new codex means new list. Having read through the new book I get the feeling that the best way to go is to try and maximize fire output and high durability.

For 1750 points:

1x Overlord
      - Phaeron
      - Warscythe
      -  Phase shifter

1x Royal Court
      -Lord
           - Warscythe
           - Resurrection orb
      - Cryptek
           - Harbinger of Transmogrification
           - Harp of Dissonance
      - Cryptek
           - Harbinger of Transmogrification
           - Seismic Crucible


20x Necron Warriors

9x Necron Warriors

      -Ghost Ark

9x Necron Warriors

      -Ghost Ark

3x Wraiths

3x Wraiths

1x Triarch Stalker

1x Triarch Stalker

1x Annihilation Barge

1x Annihilation Barge

Total:1739

I might try to fit in some mind shackle scarabs on the overlord if i can decide where to drop 4 points.


How I think it works:
Overlord and regular lord deploy with the big warrior squad which advances down the field towards the objectives/enemy.  This unit should be very hard to damage with the resurrection orb. Hopefully it will also stand up to some punishment in combat outputting 5 s7 power weapon attacks when it is being charged.  The relentless gained from the overlord means it will continue to output a nice chunk of firepower on the move.

Everything else floats along behind this unit.

The Praetorian are my counter attack unit to prevent the big warrior unit from being bogged down in combat. Alternatively being able to jump out from behind and put in a few low AP shots is nice.

The Ghost Arks protect the two smaller warrior units (which the crypteks are hiding in) and reanimate into the big unit.  I decided to spit the cryptek wargear so I could use it on different targets and hopefully slow down the enemy and give me an extra turn of shooting against unwanted assaults.

If nesessary the stalkers can tie up enemy units in combat, however their main purpose is to provide the rerolls to hit for the other units...4 melta shots never went amiss either.

I decided to use the annihilation barges (credit for the idea to Jason) for extra firepower that is resilient and relatively cheap that can keep up with the rest of the army. Originally I had a single Doomsday Ark but its shooting on the move is rather disappointing

edit:
after some thought and discussion I swapped the Praetorians for 6 wraiths. The main rold this unit fills is counter assault. with double the attacks and more than double the wounds and a 3++ invun) and fearless I think the wraiths will better serve in this role. Having crunched some numbers the wraiths will cause more kills on opponents, up to and including power armor marine equivalent.

For example against power armor marine equivalent:

Praetorians: 3.333 kills on the charge 
Wraiths: 4.667 kills on the charge 

this obviously only gets better against less durable enemies where the volume of attacks puts the wraiths at an advantage. As a bonus I could use them to opportunistically take a swipe at vehicles
