So I trying to put together a VC army with the models I have and without spending too much money.Here is the break down. Does anyone have any tips..What is pushing the line on conversions.

30+ zombies.
40-45 skeletons with two 4-man unit fillers.
10 Grave guard
10 Wraiths
10 old skeleton cavalry could be Black Knights.
Various Wights, Vampires, and Necros for heroes

Now the conversion ideas.
The Empire War Wagon converted to a Black coach.
The old 5th edition plastic bits from the starter box converted to Blood Knight using the above Black Knight skeletons.
Nagash as a Varghulf
Miscellaneous old plastics as spirit hosts.
8-10 Mummies no idea what to with these guys.

I'd like to pick up some mantic ghouls to round out the list and another 2 boxes of Grave guard, and that would put me around $100 out of pocket.

Thanks for looking.
