I'm not quite sure of the Eldar list but a general synapyse of his typical lists are something like this
farseer + warlocks
wraith gaurd
fire prisms
dire avengers
rangers
wraith lord (s)
warp spiders

can anyone give me any pointers, I haven played my Nids for quite some time since I've been using my Necrons alot.
thanks
