@Stonehambey: Its pretty much just a restructuring of the requirements (i.e. 1 hero, limited war machines, etc.), but plays like any other 500 game (just restricts an all artillery army, for example).
@lizardlover: Well, the first question that I would ask is what do you have? Without this, its really hard to give you suggestions. That said, assuming that you have a good basic selection of troops, I would say that you cant go wrong with a JSoD, 2+ units of skinks, a 10-15 man unit of Saurus (you'll prob only need a muc), and either some terradons or salamanders. This way, you can play effectively against shooty lists, and have enough manuverability to deal with lots of fast cav. Against melee heavy armies, bait the enemy with the Saurus and pick apart enemy units with your supporting troops. Dont forget to fiddle around with magic defense (take a BS of tepok on your JSoD), and if you are new to the game you might want to switch out for a skink priest sometimes to practise magic.
