Dark Eldar Army

Hi!
I'm new to WH40k tabletop. Started collecting Dark Eldar army about six months ago.
So far I'm proudly owner of: (some are ready, some still working on)
Commanders:
- Archon
- Haemonculus
Troops:
- 2x packs of Kabalite Warriors (=20)
- 2x packs of Wyches (=20)
- pack of 5 Wracks
Fast Attack:
- pack of Hellions (=5)
- 6x Reavers
- 5x Scourges
Support:
- Voidraven
- Talos
Transport:
- 2x Raiders
- 1x Venom

Can you advice me about army build and tactics?
And looking for some players around Poznan, Poland.

GW is in the process of releasing an FAQ right now that will heavily effect army builds and tactics. I'd wait until they finalize that. Welcome to The Dark City!
