Welcome to the scene man. Tomb Kings are (supposedly) a great army to play. I know a couple of the locals at Art of War
play them, one running a very traditional list, and the other, a more chariot heavy cavalry list.
I've always liked the idea of the Liche Kings of Kameri razing an army out of the sands by nothing but his pure will and desire for immortality. Awesome fluff and a good army. Great stuff!
If you're interested, we play on Saturdays. There are a couple of us, maybe 6-8 every Saturday...minus this saturday. Adepticon and all.
Come up and if you need an assistance learning the game or just want to play around with proxies and such until you can complete your army, you're more than welcome. Just don't play me. I'm a douche
