It's an LA +1 class (so not terribly optimized), but if you give them something to boost their SR (think there's a vest that does that in either the MIC or DMG II) and the Mage Slayer feats, they'd be rather vicious. Oh, and I'm going to suggest a trip build using the spiked chain and Combat Reflexes. Because once you threaten them with it, you can trip, AoO (no casting defensively with Mage Slayer in play) and otherwise harm them to your heart's desire.
Karsites can also use psionics just fine - though the OP's DM apparently frowns on that.

How about Incarnum?
