Impossible, Mage - No unit loss.

Oh right, the setup I run right now is: Evil Beholders, Inqs, Cannoners, Royal Plants and Arch mages. (With Royal Snake as a sub for no retal)

I still hold on to the arch mages due to high amount of hitpoints, long range, the shield and the teleport. Basically with rank 2 slow and the Arch mage teleport you "freeze" one mob for an entire turn. And that helps alot.
