Buckets of Wyches and Reavers to take advantage of the more reliable drugs.
Add 3 Ravagers or 2 Ravagers and a flyer of your choice and you'd be golden.
If you're feeling more adventurous, I've seen some Duke Lists take the 2 to 4 of the following unit:
5 Kabs 155 points
+ Blaster, Sybarite, Blast Pistol
The plan being to deepstrike them next to or behind tanks and blow 'em up. As a source of anti-tank in the troops slot, thus letting your ravagers bring dissies or not run ravagers.
Time for the grateful DEldar.
