1st attempt at purging CSM in 750 pt game, help needed!

Fellow archos good day,

I have only very recently been swayed from WHF into 40k and picked the DE as my poison of choice.

It's my understanding that ours isn't the easiest army to play (all squishiness considered) and would greatly appreciate help in building this first list against CSM. Here's what I roll with at the moment.

1 x haemonculus
1 x succubus
5 x wracks
10 x kabalite warriors
10 x wytches
3 x reavers
5 x hellions
5 x scourges
2 x raiders
1 x venom
1 x ravager

Like I said, this is for a 750 pts list. Can anyone help me get a optimal list with I have in hand?

Thank you and good reaving!

M.
