Having played this theme in T2 for 2 years (casually), I would highly recommend running a second copy of Seraph with a Live Coal. His band to Isaiah is going to be your bread and butter attack so you want to have an extra one. I would also recommend running Covenant with Death. Your important heroes are CBN and with Horses you should get initiative to play defensively even with your Assyrians being negated, or you can turn it off when you need character abilities. It really throws a wrench into a lot of other themes. I had a lot of success running Striking Herod for situations where the opponent either got rid of my human from a band or when I wasn't drawing into any humans.
