This is where you can post your version of the best and worst units of the necrons. Here is my list with 1 being the best. You can also list the artifacts you give to your necron lord. You can also list the reasons why you choose them.
1: Heavy Destroyer
3: Basic Warriors
4: Necron Lord (Depends on the artifacts) with Resurection orb, "The automatic healing" one and veil of darkness.
5: Flayed ones
8: Tomb Spyder
