I really don't care for Trumpet and Sword. I've tried it in a couple of decks and it just never works. So I'd drop that, Ahimaaz, Zadok, Journey, Uriah, Seraph, Valley of Salt, Seraphim, and Abishai. Which gives you 9. Also, I'd use an evil King Saul instead of a good one if you keep in King Amazing (he's called amazing for a reason).
I can never decide whether I like Mustering or not, but that's also an option.
