Martial wizard6/swiftblade9/abjurant champ5 is a classic, it gets 9th level spells and +16 BAB. If you play with fractional BAB stacking, you can pick something else for level 6. You're held out of swiftblade until 6 because of its BAB requirement. An elf of some sort (racial weapon proficiencies), neraph (proficiences due to outsider type), or other race with automatic weapon proficiencies is recommended so you don't need to burn a feat to meat the weapon proficiency requirement.
