Good tradition. I'm so happy to see people embracing Eberron again. Forgotten Realms was shoved down our throats too much, make way for the better setting ;P.

I would maybe touch up the description. It was a little confusing at first as to which class it was for. One spot makes it sound Fighter, but then it shows Wizard.

another note, your quote at the end about jedi and sith. well, if you've ever read the Sarlona book from 3.5, you'll find the 2 main Kalashtar factions are pretty much a combination of Jedi/Sith and Tok'ra/Goa'uld lol. Just thought I'd throw that in there cause that last little note gave me a chuckle.

Solid tradition, comparable to the bladesinger, even though I find melee wizards a bit risky. What the phantom knight lacks in defence makes up for in attack evasion; expeditious retreat, misty step and Aspect of the Phantom can make sure the knight stays out of trouble. Add Alacrity of the Phantom to that, and the knight turns into a deadly combatant. The only issue I can see is if the knight is restrained or grappled, most of its abilities become useless.

This is one of the best homebrew I have ever seen. Good job.
