I recently made a zombie dragon build, trying to surprise everyone in a tourney (I usually play static CR casty vamps), so I could share some thoughts with u:
The Lord:
~Bloodline Powers
*Red Fury (allows your lord to charge infantry units and easily win)
*Infinite Hatered (Dreadlance is really cool, but getting hate on your 5 str 6 attacks is...)
*Walking Death (what did I say about static CR infantry units?)
~Magic Items
*Sword of Might (permanent STR 6 is fine, because most elite troops and heroes /or human lords/ are T4, and you'll be fighting with those most of the time)
*Crown of the Damned (Wristbands of Black Gold look cool, but you basically have a 3+ ward save just for being mounted of a monstrous creature. The problem is that if u fight against something like greater daemon of Khorne he can easily kill your lord, and that's somethign we don't want to happen)
*Hand of Dust (unusual choice that needs testing, but on paper it's a bound item that can easily draw 2 dispel dices, or be really devastating if you surprise your opponent and actually get it through)
I was thinking about Nightshroud &/or Cursed Book, but I realized that smart opponents will just attack the dragon - same toughness, less WS and no saves whatsoever.
I was also thinking about Flayed Hauberk, but the same reason made me change my mind. The only thing I couldn't drop is Crown of the Damned, because if you don't have stupidity, everyone that played a few games against VC will know that at the very best your lord has 5+ ward save, and won't hesitate to attack him, and even if I have nightshroud or cursed book, I can't be sure that I'll kill my opponent in just 1 close combat.
rest of the build includes 1+ AS BSB on barded nightmare with enchanted shield and Book of Arkhan and a Lycni vampire with flayed hauberk, periapt, infinite hatered & ghoulkin - he can easily get your opponent's war machines (some times even on 1st turn), especially against dwarves that have gunner's pride and can't flee.
Build also has 3 units of dire wolves, varghulf and a 5 strong unit of fell bats for artillery hunt.
