__1500pts___

How I improve?

I'd say throw out the 2 medusae in favor of a sylth, more wounds and better T. I don't really think you need an agonizer on that haemy, a singer pistol and a scissorhand might work better as you can shoot both stinger and splinter pistols. Instead of a HL on the Talos take the SC or HB, 1 str6 ap1 lancemelta shot wont be threatening enough against MC and is worse than the HB when going for vehicles, besides you could just charge the crap out of anything with Dark Artisan.
It might be wise to drop the WWP on the RSR, as you could just start the venom on board and flat out it turn 1 to get into position,unless you feel like deepstriking the scourges instead . I am guessing you will be going for a -4L combined penalty with the shadowseer, -5L with covens and potential -6 due to death jester. Consider reducing the amount of artifacts your DA haemy is bringing, Vexator mask is not really that awesome.

Wraithguard will counter you hard on this as your Dark Artisan cant handle that stupid flamer bs. Mechanized armies too will give you headaches. Anyone with too much psychic dice to spare is going to give that sole shadowseer hell of a time, literally.
