NOVA dark eldar grey knight list

Saw that a couple people in the NOVA tourney were using Dark Eldar with Grey Knight allies. Does anybody know what this list might look like and how its used.

Thanks

I don't know what it would look like but here is what I have to say

Hello Human, look at your army; now back to mine, now back to your army; now back to mine. Sadly, yours isn't like mine, but if you left 6th edition and switched to 7th edition you could have one just like mine.
Look down, back up, where are you? You're in the store with the rulebook your rulebook can't play like. What's in your hand? Look at me, I have it, it's an army with Inquisition and Daemons that you could only hope to have.
Look again, the army is now Ultramarines and Black Legion. Anything is possible when you play 7th edition so stop with 6th.
I'm riding a Carnifex.

They could have been planning on using lots of psychic powers in their list, and threw in DE allies to get a haemonculus w/ crucible of malediction. Crucible is actually pretty worthwhile now, as against a psychic heavy list that has 30 points of warp charge, you may very well be able to kill 500 points of characters with a 20 point item.

But, that's just my first thought. Hard to tell without actually seeing the list.
