I usually don't love builds where their schtick is just a few times a day ability. Unless, I suppose, the ability lasts the entire encounter anyway. That being said, it's probably not a big deal in this case. It's not hard to get a lot of Abrupt Jaunts per day, since it runs off of your Int modifier. And, you'll have all the other means of teleporting around, too.
Just going ye olde gish probably works really well, just b/c it always does b/c Wizard > most things. Even if you are setting a lot of caster levels on fire to get to Shadow Pounce. Although I'm sure there are other interesting options.
