1500 points for a league

Hey there Been lurking for a little while, but the deadline for submitting our army lists is approaching, and I thought I'd ask for some opinions on my list. My opponents will include at least 2 Blood Angels, 2 Dark Angels, Necrons, Tau, Daemons & Chaos Marines. There may be some more that I don't know about too. AFAIK there aren't going to be any Orks, Tyranids or Eldar. I know there's a triple Heldrake list and a CronAir list.

Here's what I was thinking...

Sliscus
3 Haemonculi w/Liquifier gun
9 Wyches w/haywire grenades, inc. Hekatrix w/Venom Blade in a Raider w/Aethersails & disintegrator
9 Wyches w/haywire grenades, inc. Hekatrix w/Venom Blade in a Raider w/Aethersails & disintegrator
9 Wyches w/haywire grenades, inc. Hekatrix w/Venom Blade in a Raider w/Aethersails & disintegrator
2 Ravager w/Night shield
4 Incubi inc Klaivex w/demi klaives in Venom w/extra cannon
6 Reavers inc Arena champion w/Venom Blade, 2 Cluster Caltrops

Any thoughts, comments and criticisms would be greatly appreciated. I've played a grand total of 3 games of 40k in the last couple of weeks so anything will help

Thanks in advance

How are you going to deal with the triple helldrake list or the CronAir list??? You have nothing other than hope and 6s to hurt them. Also by taking dissies on the raiders you have lowered your darklight alot, bringing even less chances of hurting them...
