Generally you don't take anything but scythes and tombships. The shrouds will make you lose, because of the way necron vps work.
So a list would look like this:
1500:
5 Scythes 1375
Then some re-rolls, or Dirges, if you feel the need to use all the points.
Alternately, you can take this:
1 Tombship
+sepulcher
3 Scythes
Re-rolls and dirges as necessary.
