Coven/Kabal 1750 pts tournament list

Greetings fellow Lords of Commorragh.
In about a month I'm going to take part in a tournament and I've decided to suprise everyone by not playing with my beloved wyches
Instead I was thinking of playing something like this:

HQ (185)
Archon
- VB, Shadow Field, PGL
Haemonculus
- LG, VB


Troops (505)
Kabalites, 10
- 1 SC
- Raider (DL) with NS
Wracks, 10
- 2 LG
- Raider (DL) with NS
Wracks, 5
- 1 LG
- Venom with 2 SC and NS


Elites (506)
Trueborns, 4
- 2 SC
- Venom with 2 SC and NS
Trueborns, 4
- 2 SC
- Venom with 2 SC and NS
Grotesques, 4
- 1 LG
- Raider (DL) with NS


Fast Attack (324)
Reavers, 6
- 2 Blasters
Reavers, 6
- 2 Blasters


Heavy Suppoert (230)
Ravager
- 3 DL, NS
Ravager
- 3 DL, NS


As of right now I know I'll be going up against 1 Nid army, 1 Daemon army, 1 Wraithwing army and probably 1 Guard army.
Now the Wraithwing and Guard player I'm not that sure what they will bring (except for you know, wraithguards..) but from what I understand they won't be packing their lists full of fliers.
Now the Nid player will bring atleast the following: 1 Flyrant (with 2 T-L Dev.), 2+1 Zoranthropes, 2  Biovores, 1 or 2 Tervigons and at least 10*3 Termagants. Since I normally play wyches it will be nice to just sit back and unleash my splinterweapons against him
As for the daemon player she'll probably bring  pink horrors, flamers, screemers, D. princes and hearalds of Tzeentch. Plus some Plaguebearers to camp on objectives and maybe some bloodcrushers.


Now what I wonder is how do you think my army will do against these four armys?
I also would like one more Troop to claim objectivs with.. Any ideas on what to remove to afford this?
