This may just be me, but I perfer cards who search for specific cards. with that in mind I would switch out John for the Magi ( to search for ALL of your arts especially gifts) and I would add search for your green guys and switch out prosperity for great faith.
If you want to take something out to put in search, I guess I would take out plague of Frogs because you are probably going to use hurr even if you dont have it. I also agree that adding provisions is a good idea.
