I am a newb to warhammer 40 k. I decided on Eldar as my army of choice. I am not really very sure of how to compose the best army list or how to determine what is most competitive. So far I have an old eldar battle force -the one with the War walker-, a Fire Prism, 8 Eldar Scouts from the 80s and 90s, a box of Eldar Rangers, a Farseer, Prince Yriel and Illic Nightspear. I really like the Iyanden craft world and am partial to magic. What suggestions do all of you have?
