40K - Call to Arms Dark Eldar List

So we have the Warlords annual convention Call to Arms coming up the first weekend in August. At it there is a five round 1750 point 40k tournament sponsored by Mighty Ape.

It has attracted 42 players and I am looking to take Dark Eldar along. I rarely get to attend two day events (my last was CTA in 2017) so I am looking forward to it.

There is a restriction to two Detachments - as per the FOB NZGT - and I am using that to take one each of Kabal and Coven. I am surprised I'm the only Dark Eldar player in the field as I'd heard that they were belle du jour.

Here's my list:

Kabal of the Black Heart Battalion
Archon - Blaster, Huskblade, Relic - Writ of Living Muse, Trait - Labyrinthine Cunning [Warlord]	93
Archon – Blaster, Venom Blade	89
5 Kabalite Warriors - Blaster	47
5 Kabalite Warriors - Blaster	47
5 Kabalite Warriors - Blaster	47
Ravager- 3 Disintegrators	125
Ravager- 3 Disintegrators	125
Ravager- 3 Disintegrators	125
Raider – Dark Lance	85
Venom – Twin Splinter Cannon	75
Venom – Twin Splinter Cannon	75
Prophets of Flesh Coven Battalion
Urien Rakarth	90
Haemonculus - Eletrocorrosive Whip, Hex Rifle	81
5 Wracks - Ossefactor	52
5 Wracks	45
5 Wracks	45
6 Grotesques	210
Talos – Haywire Blasters x2, Chain Flail, Scalpel	98
Talos – Haywire Blasters x2, Chain Flail, Scalpel	98
Talos – Haywire Blasters x2, Chain Flail, Scalpel	98

It competes in three of the four phases in the game. Last year I finished 6th out of 24 so I'm aiming to see if I can make top 25% again this year.
