Well, Romans + Phars would be a good defense to go with. It would have a decent bet of stopping power, and a phar bit vIttle drawing. This would have decent stopping power and have some speed too.
Herods however, would be the 'larger' defense of choice for me in terms of getting more blocks.
Your choice, Phars + Emporers would draw a fair bit, but Herods would probably net you more blocks.
Anyway that's my
