>Stalk for dinosaurs
Hoooooly crap. This enables me to have a TRULY stealthed force. Now if I could also stealth my Skink Priest, I'd be able to launch battlefield-level ambushes in every situation. OR! Just get rid of the Priest, and have a Skink Oracle as my only spellcaster.
I'd personally use Bastiladons with Arks of Sotek as my army's melee tanks. They're highly durable and their AoE snake abilities will do a good amount of damage in the crowds they're sure to attract. I'm still not decided on whether or not I'm sticking the Dread Saurians in Oxyotl's army.
