Hordes are tough especially legions of nagash. I played against them with a 7 man nighthaunt warband (15 models in the legion list. I got lucky by having 2 rounds with quad 5s for reap like corn with my grimghast. As he was so bunched up it hit nearly every Skeleton. Had it not been for that I would have no way to win. Don't let the 3 inch move fool you they can be quick with van hels ability
