I'm in a toss up between a brown Persian defense, and Gabe's suggestion of orange/Phillies. Originally the defense was orange/Phillies, but I switched it around. I like having Herod's to withdraw hero's and brown Persians to set aside hero's. It's not only a lot of fun, but it constantly keeps hero's set aside/captured/out of battle, all using just the SA's on my EC's.
