I'm putting a unit of 15 Black Guard into my next army (2000 points) and was thinking of taking a magic banner for them (not bsb so max 50 points). Enemies will be wood elves, warriors of chaos, or skaven. Banner of Hag Graef is out: Black Guard are faster than anyone short of high elves anyway. Dread Banner is only 10 less than the wailing banner, so no reason to take fear when terror is an option. Banner of murder would be good against WoK, but unnecessary against skaven or wood elves. Anyone have advice?
