If you really want to be nasty and despised by your friends you should drop the witch king and find a way to take the tainted and dwimmerlaik. Just spend a point of will to keep your opponent from using mwf and with me within 12 inches. You already have a shade, just go full spectres and kill on courage, with the -1 from the wraithes. Imagine D4 high/galad elves with -1 to the fight roll! And the heroes act like banners!
I am not bitter about playing against a list like this at all, nope not at all.
