Pure covens list

Alright so I've been trying to get a solid well rounded list for my covens that I can use to take on most anything at friendly pick up games built at 1500 points. C&C and any tips you have as I'm still new to the hobby.

Primary Detachment
Dark Artisan (395)

Haemonculus; Scissorhand; Flesh gauntlet; Stinger pistol; The Nightmare Doll;
Chronos; Spirit syphon; Spirit probe;
Talos; Ichor injector; Twin-linked haywire blaster;

Secondary Detachments

Scalpel Squadron (260)
2x - 5man Wrack squad w/ Ossefactor Venom w/ Splinter cannon

Grotesquerie (355)

2x - 3man Grotesques; Aberration upgrade w/ scissorhand
Haemonculus; Scissorhand; Flesh gauntlet; Stinger pistol; Syndriq's sump;

Scarlet Epicureans (490)

Haemonculus; Hexrifle; Agonizer;
Chronos; Spirit syphon; Spirit probe;
2x - 10 Wracks w/ 2 liquifier guns

Get a heat lance on your talos and a wwp on the dark artisan it is way to slow not to have one. I'm guessing you are not doing ITC since you have more than 3 detachments

Right on so heatlance and WWP
I just play pick-up games with friends and at local stores wanted to make sure i dont play to loose.
