My first game with the codex was against Grey Knights, literally right after I was given it as a gift.
He split his army in half, a dreadnought and a couple of boots on the ground in his half and the other with a dreadknight and all of his good stuff.
He cowered in our particularly large cover, but it didn't help as most of my units were kabal of the Flayed Skull in transports and the others were Asuryani Rangers and a farseer. The dreanought died turn 1 and I killed most of his ground troops. Then, the interceptors re-deep-struck and the rest of his army appeared behind me. My splinter re-rolls were handy at wiping out his infantry and the increased speed also allowed all of my vehicles to run to safer covers with objectives.
Overall, Grey Knights are terrible and we won
Newbie Drukhari player (so new I call them Drukhari, not Dark Eldar)
Most of my armies consist of entirely Kabal of the Flayed Skull.
~2000 pts army, ~1500 pts built army, ~1400 painted army, ~650 pts of finished army!
