Well - without a doubt - HQ - Eldrad and Farseer. Farseer - Guide , Fortune.
Psychic powers separate Dark Eldar from powerfull to murderhouse.
Doom and Fortune will empower Wyches tremendously. 4+ save, 4+ reroll , 4+ FnP, thats close to Terminator.
Forget about Autarchs, you need 2 seers.
Troops - Wyches 2 Squads Haywires+agi+Shardnet, seers with them,
Warriors in Venoms - 4 Else.
Elite - 3 Wave Serpents with Fire Dragons. Transport Popping Obviously.
Heavy - 3 Ravagers, Flicker Field.
Fast Atack - Something from our codex - Eldar is lacking in this slot. Fortuned/guided scourges seems nice. Maybe reavers. Rerollable 3+ , its like Seer Councile.
Fire Dragons in raider will get nothing. They will be shot down easily and first.
