Knights are a bit pricy... I guess it'd be a distraction! My thought just to mob anything scary with plague zombies to allow them to kill 3pt models with 4+
FNP for a few turns haha. Maybe I should get another 30 plague zombies to tie up enemy heavy hitters andgenerally get in the way? I could potentially switch a horror squad for them.
I'm strongly tempted to get a tzeentch army - they do look fun to play
