1500 pt Highlander List

Hey everyone, I have a 1500 pt Highlander ITC tournament on saturday and this is the list I've come up with. I feel like other armies like tau have an advantage in highlander as they can still take a riptide and 3 broadsides, but I feel like this is a pretty solid list for pure DE.

Custom Coven Battalion (Dark technomancers, obsessive collectors)

HQ
Haemonculus - splinter pistol, venom blade
Drazhar

Troops
5 wracks
5 wracks
5 wracks

Elites
8 incubi - demiklaives

Heavy Support
Tantalus

Transports
Raider - desintegrator
Raider - desintegrator
Raider - desintegrator

Black Heart patrol

HQ
Archon (warlord) - blaster, huskblade, writ of the living muse, labyrinthine cunning

Troops
10 Kabalites - 2 blasters, 1 splinter cannon
10 Kabalites - 2 blasters, 1 splinter cannon
10 Kabalites - 2 blasters, 1 splinter cannon

Lemme know what you guys think, the other alternative is to trade out the raiders and 10 man squads for venoms and 5 man squads and then that gets me a ravager and razorwing in the black heart detachment, but I'm not sure.
