I'm pretty sure Cursed Razor has been finalized, but the one in the document might not be the final version. Either way, unless they significantly rework the discipline, it should stay as appealing.

Either way, if you were going to mention the Martial Training feats, you can just mention that it has quite a lot of potential, since it could be really complicated. However, disciplines that have an Int skill would be the most likely ones to be best: Cursed Razor, Shattered Mirror, and Elemental Flux are the big ones I can recall off the top of my head (though with Bruising Intellect, Black Seraph and Eternal Guardian might also work).
