Vampire Count Build (Blood Knights Unit)

Hi all,

I’m wanting to put a Vampire Count on Nightmare in my unit of Blood Knights but am unsure how to build her. I really like the idea of giving her the Sword of Kings rather than a lance, but I don’t know if that would be optimal/viable.

I was also curious whether anyone has tried a VC on Nightmare with a blender build (Level 3 wizard with illusion/spectral doppleganger). I know people have had success with this on foot (in a unit of Grave Guard), but wondered if it could also work with a cavalry unit.

Or would I be better off just making her tanks and forgoing the wizardry? Any advice greatly appreciated.
