this looks fairly similar to my FBTN deck. I've found you really don't need that many multi enhancements. I only use 4 and a Godspeed and Covenant of Moses. you definitely need more heroes. I use Moses, Benaiah, Captain, TSA, Ira, Hur, Joiada (as you can see, I like to mix in some speed. it helps), King Asa (to get rid of Asherah Pole), Jacob, Seraphim (blue). you can get a captain band going quickly that way. since you can't do RoA on, Joiada is kinda worthless...but Hur should give you the speed to get a Captain. the defense is small, which I normally like, but without all the spam of multi color, I use Emp Nero, Prince, Seven Sons, KoT, Uzzah, Ammy Slave (kinda hard without RoA...), Possessing Demon, and Sabbath Breaker. I really need to throw in a Philistine Garrison, but haven't got around to it. a Lying unto God is super helpful when you already played DoN on their Holy of Holies and they activate Golden Calf. it's also nice on KoT. you definitely need a Philosophy in here though.
take out the Joseph's Silver Cup and add a Lampstand or a Writ.
