1,200 Dark Eldar Army (Duke, friendly *new-ish player*)

[i_zimbra]

So after a 8 year sabbatical, the re-released Dark Eldar have gotten me back in the game. Currently, I just play a friend of mine (who fields Eldar). We're slowly moving up to bigger games, but as of right now we're doing 1,200

HQ
Duke Sliscus (150pt)
Homonculi w/Webway Portal (85pt)

Troops
20x Warriors (180pts)
4x Wracks (40pts)
15x Wyches w/3 upgrades (180pts)

Elite
5x Incubi w/Klaivex w/Onslaught (140pts)

Heavy Support
Cronos Parasite Engine w/ Spirit Vortex (110pts)
Voidraven w/4 missles (185pts)

Transports
2x Venom [1 for Homonculi and Wracks, 1 for Incubi] (110pts)

TOTAL = 1,180

Basic Idea:
* The Duke is deployed with 20 warriors that get 3+ poisoned weapons because of it. Placed in the middle, trying to cause trouble and draw fire.

* Move Venom w/ Homonculi and Wracks 12" 1st turn, disembark and place WWP

* Wyches in WWP reserve

* Incubi and Voidraven either Deep Strike or WWP

* Cronos probably deployed at beginning of game like normal


Questions:
* Do I have enough anti-tank pieces?
* Do I have enough units? Meaning: will the Eldar player be able to pick apart my army easily?
* Is there anyway I can fit Mandrakes in here (150pts) I like the models a lot and they seem fun.

F the Mandrakes - I'll find a place for them in the future. Instead I decided a team of 4 Trueborn on a Venom with Shredders would be nice for 123.

In turn I sacked 4 wracks, 1 wych + upgrade, and 4 warriors.

Meanwhile, I gave the warrior squad a dark lance and splinter cannon.


Question:
If you were an Eldar player, what would you take to destroy this army? What holes am I missing?
