I played a game the other day and realized how well my destroyer lords had done for me in recent game(and pretty much every time I have fielded them with wraiths for that matter) and wanted to work on a list based around them. My local players hate wraiths(because they have a 3++ invuln save

),
MSS(

), and flyers so they are most likely not going to enjoy the list very much.
The plan is to rain down destruction from the Sky shield landing pad with 2 doomsday arks parked on it for a 4+ invuln save and great line of sight. The wraith squads will move forward and take out parts of the enemy army that try to hide. The immortals will come in with the night scythes to take out things near objectives and grab them for me.
