Attack Order

[thejeff]

Isn't that a little tricky since the standard Earth Air Tart cyclops doesn't have Astral?

And unnecessary. If you've got more magical back up with your army, which you should at this stage, just have someone acting before the tart cast Fog Warriors or Army of Gold/Lead. Your buffed army will shrug off RoS.
Or if your tart Cloud Trapezes in and kills the defenders with RoS, then there won't be another fight when the army moves in, unless the other side is also moving a new army in. If there is a second fight, you're not likely to have the gems left for more RoS, so your army will be safe.
