[Mr.Blonde]

For months now I've been at war with the task of creating a solid 1500 pt. force of Necrons and have found some dificulty finalizing some unit choices. In particular the Tomb Spider. The general premise of the army list is to create an overall good force of crons capable of handling most anything, and I was wonering if tomb spiders even belong? Would they be overall good or overall bad? Need help!
