I would take Angel of His Presence, The Rabshakeh, King Tiggy, Harvest Time, Unholy Writ, Feast of Trumpets, and Hosea, and add Gomer and Haman's Plot. Angel of His Presence, while theoretically good for drawing off of Isaiah, is nothing but fluff, and thus, a pretty easy cut. I understand using the Protection of Jerusalem strategy, but you still have too many evil characters, especially since most defenses that aren't the meta will be using some kind of a protect fort. This deck is slow enough that you shouldn't find too much use with Harvest Time. Writ is a hard cut, but in my experience, it doesn't really function as a battlewinner on its own anymore, and with your larger defense, you should be okay. Feast of Trumpets is nice with Gifts, but I think that more like than not you won't get a chance to use it often. Hosea is mostly fluff. He has a nice ability, but I'm not really feeling it in an Isaiah deck. I'd add Gomer and Plot because it helps round out your defense and gives it a lot of extra oomph.
