Minor feedback here, the Mystic Theurge is lacking access to a number of skills it likely should have access to, such as Craft Armor and Weapon (Class skill for every other class), Knowledge (History) [Class skill for wizards, sorcerers and clerics], Knowledge (Nature) [This one is debatable, but playing a druid theurge with no access to knowledge nature would get a little wonky, especially at epic levels)
