So guys, I was bored and was looking at my codex, on the different uses for close combat and ranged-guass cronz,(Tank Busta's) and I've come up with this; necrons are the most durable army in the entire game, so with these as an army list i thought it would be more than effective, ESPECIALLY against tanks!!! so its like this, for your HQ take a character or an overlord to ride in an Catacomb Command barge, with a guass cannon, you also want two ghost arks carrying 10 warriors each and broadside your way to flank them with a a few 10 model units of immortals with guass blasters going in for a frontal assult, with a few lychguard with warscythes as some insurance, you also want a veritable swarm of scarabs going through the battlefield with a spyder to make mor of them, you want a large scale force of wraiths behind a squadron of lychguard with shield going in from the other side, the better to flank them, you will want a doomsday ark or two in the back blowing them to pieces with the doomsday cannon, and to mop it up, (if they survive) get some tomblades or destroyers to help with cleanup, and remember, there can NEVER be enough immortals!!! ~Trygonz
So what do you guys think? threw this together in about 15 minutes.
