So this is a 2000 poont necron list that i saw yesterday being playedat my local game shop, at it is actually really fun. I have toyed around with making a list like this since the codex first came out. I will just cut to the point and give you guys the list.

Orikan the diviner
Immotek the stormlord
+ 5 lychguard in a scythe

Ctan shard with worldscape and singularity

4 units of seven warriors each in scythes

Then 3 doom scythes

First turn start with the ctan on the board and alpha strike everything else.
This was fought against by a space marine list with vulcan and rifleman dreads and everything. Put it this way, by the end of turn three, marines had 4 moving models left on the board.
