Horus (one of ra's Mythic Age Minor gods) gets the tornado, which flings units, trees, ect all around...
and it says that you can be "evil" and transport enemy units into a walled area, surrounded by towers, lions ect =/
now wouldnt it be evil to wall a specific area off, add those ballista towers we saw, and save your shifting sangs AND Tornado, then transport the enemies army to the "prison" then lay a tornado right smack dab in the middle of his units! that might not be very cost effective wasting two GP on one army, but im sure it would be funny the first time
they aren't smart enough to make their own.
