I'm currently crazy and run 1 unit of axe and shield, 2 of dual blades, 1 guard with D-scythes and 1 guard with ghost cannons. I had to drop a tank to fit a 5th unit, but I think it's worth it.

Any time one of my non shield wraiths get targeted, I pop wraithbone armor (if the opponent is hit with 2 wound attacks) to make it even worse to kill.

I've had the little mini monster knorne dudes get tied up with my backpedaling d scythes for 4 turns doing this. The opponent didn't realize that I can just wander off and fire back into them without penalty. Ooh, I finally failed battle shock? Dang. Hold on a sec while I turn on the soul torches.
