Necron 2000 point list

This list is dangerously lacking in Troops for a generalist army list. Only having two scoring units could really end up hurting you in the long run.

After that, I'd look at simplifying the Lord a bit. Necron Lords are generally a support HQ that is best left to projecting a Res Orb and granting a little extra power in the case of a charge to one of your Necron units. You could also very likely stand to drop one of the Heavy Destroyers.

REALLY needs troops, other than that though, looks like a fine list.
One thing to keep in mind, Pariahs are a 0-1 choice, you cannot have more than one squad of them, so keep that in mind.
