I really like the idea of using Anrakyr in my upcoming Necron army. But I have heard that he is not that good. I planned on running him in a Command Barge to fly over units and carve them up while utilizing Mind in the Machine, but I have heard that this is not legal. I guess I do not understand the acceptable usage of this power. Can someone with a bit more Necron experience elaborate on effective, legal ways Anrakyr is used in some lists?
