Im sorry, I didn't fee like reading all the posts so if this was mentioned (and I don't think it was cause this should basically prove a foolproof way of defeating him) excuse me.
Spells Needed: Forcecage, Contingency, Acid Fog, Teleport, Greater Blink, Dimension Door Greater, Mirror Image Greater, Otilukes Resilient Sphere, Celerity, Dimensional Anchor, Invisibility Greater, Orb of Force, Fly, Alter Fortune, Dimension Leap, Celerity Lesser, Nerveskitter, True Strike, True Casting, I mean, you really don't need any more, most are just for extra protection anyways.
Feats Needed: Quick Recovery, Improved Initiative, Quicken Spell, Acidic Splatter.
Items Needed: Belt of Battle, Vest/Cloak of Resistance (to get a higher will save), Mithril Twilight Chanshirt +5, empyreal (not for AC bonus, always put bonus to saves, yes I know you're not proficient, but again, you don't need it for AC), Headband of Int, Gloves of Fortunate Striking, Rod of Maximize (you don't need it but it makes it go quicker, and only if you can afford it, I didn't bother to check prices).
Class Abilities Needed: Conjuration Specialist (abrupt jaunt substitution feature); prohibited schools, enchantment, necromancy.
To prevent being charged and killed in the first round do something like: Contingency - activates if I am flat footed and attacked - casts Dimension Leap.
Obviously use Nerveskitter to get a bonus on initiative, in case you don't win, the contingency should save you. Should have at least a +11 bonus (nerveskitter, belt of battle, improved initiative) and thats assuming you have a 10 dex, which you shouldn't.
Cast forcecage around him (barred version), then use 2 charges from your belt of battle to cast Acid Fog (maximized with rod) if you have it. Repeat acid fog if not dead in 14 rounds, you can also hammer with acidic splatter or orb of force since its the barred version.
If he happens to have a teleportation item or something that you know of, use a quickened truestrike then dimensional anchor beforehand. If he happens to have one you didn't know about beforehand, use it afterwards, then repeat the forcecage/acid fog (you should have an extra forcecage if your int is high enough). If you happen to roll a nat 1 on the dimensional anchor use gloves or alter fortune...if you roll a nat 1 again you can just claim that it was horrifically bad luck and shouldn't count because realistically the chances of that happening are very low.
I mean, as long as you have celerity and quick recovery he shouldn't be able to touch you. Your will save should be high enough because you are a wizard and you have both a vest/cloak of resistance and the empyreal bonus.
You also have abrubt jaunt, mirror image greater, fly (can he even fly), invisibility greater (if you know he cant see invisibility).
If you get really desperate you can put a resilient sphere around yourself, cast greater dimension door, and move out of it as a move action on your turn, attack, then either use abrupt jaunt or celerity lesser as an immediate action when he approaches you to return to the sphere.
Also, dont neglect greater blink (if you even need to) it basically prevents you from being grappled, though, since abrupt jaunt or dimension leap dont have somatic components it should be pretty easy for you to get out of a grapple anyways.
If you run out of spells you can attack him with acidic splatter, just keep one acidic fog memorized (and you get an extra since you are conjuration specialist).
I mean, with this kind of a mage it would be hard enough for a caster to beat you let alone a warblade. I don't know exactly what a warblade can do but it should be nearly impossible for him to defeat you with a build like this.
I mean, this is just a basic build for me, I'm sure I could do better than this, but I don't think its needed. If I am missing something, please let me know.
