That's a weaksauce wizard build...
Something more like this:
Fire elf Transmutation Domain combat Wizard 5 (1st and third sub levels) with a hummingbird/ Incantatrix 3/ Mindbender 1/ Incantatrix +7/ Archmage 2(SLA on a ninth level spell and arcane reach) / Loremaster 2 (bonus feat and lore)
Notable feats:
Mindsight, extraordinary spell aim, persist spell, arcane disciple(war)
Notable items: Cunning weapon, nothing else really matters because buffs supersede the equipment on most stuff.
Initiative:
0ish dex, 5 nerveskitter, 2 eager, 5 warning, 8 familiar, 4 sign (via a wand), 4 improved initiative (screw you scribe scroll!) 2 belt of battle = +30
He has a pretty solid chance to win initiative, but he's a dire tortoise with celerity (and a wand of favor of the martyr in his shapechanged familiar's hands) so he just goes first against anyone that isn't also a dire tortoise with celerity *and* a higher initiative (I might have missed a few boosters, but being killed by your own build is kinda a win anyways).
Once he wins initiative (he doesn't get surprised because he's an incantatrix with permanancied spells like detect invis and all day long arcane sight), he shifts into a combat form (pick one) and grapples his enemy to death* (extraordinary spell aim on antimagic field).
Yes, a grapple wizard.
Why? Because that's how wizards with style kill their enemies.
*The grapple damage is going to be so obscene that it doesn't even matter what they can do the next round because about 500 points of damage will kill just about anyone at this level.
This is what the real challenge should be. Kill the grapple wizard
