I have a sizable Necron army. It's the old 5th/6th/early 7th edition Silver tide build. 3x 20 warriors, 10 immortals, 2 Monoliths, 2 ghost arks, a doom scythe, annihilation barge, Anrakyr, Trayzn, Varguard Obyron, Some generic over/lords, a tomb stalker, 3 Wraiths, scarab swarms, canoptek spyder, 5 lychguard, Triarch Stalker, and 3 tomb blades.
That's more or less it, and I really don't feel like adding more to the army at the moment. Is silver tide still viable?
