I made this list after little thinking. I've learned that space marine players like to use their lascannons to kill big monsters and destroy heavy tanks, so i decided not to put a monolit or c'tan in the list. I also replaced the destroyers with wraiths, as they get nice 3+ save even from lascannon, so I think they will survive much longer. Here's the list.

HQ:
Necron Lord
- Destroyer Body
- Phylactery
- Phase Shifter
- Warscythe
185p

Necron Lord
- Destroyer Body
- Resurrection Orb
- Phylactery
185p
These guys work together, and i think they will survive pretty well. The first lord might try to destroy those predator tanks.

Elites:
8 Immortals
224p
Gives fire support to wraiths, scarabs and lords

Troops:
15x Warriors
270p
15x Warriors
270p
You gotta have some mass too.

Fast Attack:
3 Wraiths
123p
3 Wraiths
123p
10 Scarabs
120p
Think to get all these and two lords in CC with you.

Total:1500p
Necrons: 46
Phase Out: 11

So what do you think about this list?
