Here's the first 7th edition army list I came up with: Slaan Mage Priest Focus of Mystery (knows entire lore) Rocused Rumination (free power dice) Skink Priest Ancient Stegadon w/ Engine of the Gods Level 2 wizard Skink Priest Level 2 20 Saurus Warriors Spears Full Command 10 Skink Skirmishers Hand Weapon & Blowpipe 10 Skink Skirmishers Hand Weapon & Blowpipe 20 Temple Guard Full Command 3 Terradon Riders 1 Brave 2 Razordon Hunting Pack 2 Salamander Hunting Pack
You've got a decent force there. May I suggest dropping the TG unit down to 16 and giving the sking priests a dispel scroll to. There also aren't many magic items as well, but apart from that a well balanced army.
