It does seem to be your list, to a fair extent. Dark eldar do not fare well on foot, and you lack reliable AT from a distance. However, with what you have it can be done.

Lilly is a good looking model, but she rarely justifies her points. Consider using her as a succbus. I would use your archon as an HQ instead. They are cheap, and quite killy for the points.

Bloodbrides are just overpriced wytches that don't score, and really need special weapons to be useful. Like wytches, they need to be meched up as they will die the minute any gun is pointed at them.

Mandrakes are quite possibly the worst unit in the codex, but they do look cool. Run them as wracks, they will fare better.

Kabbies do well in raiders, but not with a dark lance. Generally kabbies are in raiders to shoot infantry using just their rifles and splinter racks on the boat. Since you don't have another raider, have them sit back and snipe with the dark lance, giving their raider to the wytches(run them 10 strong, or 9 plus an archon or succbus).

Reavers are good.

Scourges should never take a dark lance as it is a heavy weapon. Give them two haywire blasters, or 2 heat lances/blasters. The haywire blasters are ok, but the other 2 guns can actually destroy armor reliably and work well with the shardcarbine range.

Razorwing can grab night shields instead of a cannon. Since you are probably using the 2 lances and 2 missiles until you run out of missiles, the cannon won't come into play till turn 5 minimum. Shatterfield missies are decent if you want to upgrade.

With what you have, I would run something like this.

Archon: Shadow field, blast pistol, venom blade, drugs

5X wracks w/liquifier(use your mandrake models). In a venom with 2 splinter cannons, night shields

9X wytches: haywire grenades. Raider w/night shields, aethersails.

10X kabbies: dark lance.

5X scourges: 2 blasters, solitaire w/blast pistol

3X reavers: cluster caltrops, blaster

Razorwing: night shield, flickerfield.

Not totally optimal, but good for what you have. I threw the blast pistols in there for some extra anti tank. It comes out below 1k so you can add some stuff as well. Maybe a hekatrix with stuff.
