Important stuff:
Normally, he has a BAB/Cl of 16/19, but because of his ability to cast Divine Power and the Abjurant Champions 5th level ability causing Cl to equal BAB, he becomes a 20/20 Gish. He also can cast any spell on the Wizard/Sorc class list from the SRD, with the DM being able to add more from other sources, and not have to pay for the spell for 9 days, with 1 round of preparation. He can also abuse DMM Persist, so that 20/20 is all day long. He also has a tiny number of Paladin spells, which are unimportant for this build.
Why this works: Arcane Disciple gives him the spells from the War domain, Paladin gives him the BAB to qualify for Abjurant Champion; because of Sword of the Arcane Order, Paladin levels count as Wizard levels for the purpose of determining Caster Level. Abjurant Champion's Capstone causes Cl to equal BAB, unless your Cl is higher. MotAO just adds access to all Wizard/Sorc spells in Core.
Sadly, without the spellpool, he only has the access of a 14th level wizard, but MotAO fixes that problem.
I would also like to say that this is my first really optimized build.
