Ooh, I really like the effect on Phase Overdrive preventing opportunity attacks during the charge, that's super clever. And I like the line-of-effect disruption on the Disruption Field Nucleator. Is the Mirror Blade supposed to have the same effect at 1st and 5th level? Judging by the 9th-level feature, it seems like no? The flavor of it is cool, but ultimately just granting surges isn't very exciting mechanically, would have liked to see much weirder effects there.
