Here is a Night Lords List using the rules listed here, Night Lords Additional Rule set (Cant make a set of rules without at least having fun making a list)This list is simply to take advantage of Chosen's ability to infiltrate into forward positions on the battlefield.
Our chaos lord simply starts hidden and moves across the field of battle joining forward infiltrators as he moves.
Our Chosen in rhinos are to provide extreme prejudice against moving heavy armor trying to get into our ranks and are encouraged to race around and blow up armor with their 5 melta guns, and to contest objectives where needed.. These chosen would be designated Elite choices.
The rest, including two Assault chosen squads would be our troop choices using the night lords rules linked above. Obviously the assault chosen advance, while backed up by heavy plasma/autocannon fire positions.
The entire army is backed up by chaos glory and has 81 units on the ground. Lots of ap2 weaponry, melta bombs, and sets of lightning claws. 16 plasma guns, 4 autocannons. 12 melta guns, 14 melta bombs, 8 sets of lightning claws. A fun list, that starts off in your opponents face.
