Alright, I have a question for you all:
How good would an all Divination Wizard be?
For the purposes of this discussion, the Wizard specialized in Divination, and was banned from taking all the other schools (just roll with it.)
He has all the specialist Diviner ACFs from Unearthed Arcana and Spontaneous Divination; if you want, you can replace the boosts to some spells they get with the Immediate Magic (Divination) ability.
How powerful would this guy end up being? After all, even though Divination results in you knowing everything about what your opponent is planning, you have no Die to go with your Scry, as it were.
So, how would you optimize this? What feats and PrCs would you use?
Remember, all schools other than Divination are banned, which means that they aren't on the Wizard spell list for all intents and purposes. Yes, there is a set of feats that unbans a school of magic, but you aren't allowed to use any of them; it violates the spirit of this challenge.
