Behold! The enemys vile 1000 pt list! To aid Brothers!

I got a good luck at my rivals list, and here's what he's got going for an 855 list so far. He is thinking of putting Kharne the Betrayer in too, once he gets the cash. I plead for your aid in a Grey Knight counter list for this, the challenge is no Land Raiders. This game will be my first Batrep, most likely saturday, so I would like to prep up an effective list to take my Chaos rival a peg down. He's so bloody arrogant that for the Emperor he must be taken down

His list is as follows:

Daemon Prince=110
Mark of Nurgle=20
wings=20
Nurgle's Rot=15
Total=165

two squads of 9 Berserkers and a skull Champion
9 Berserkers X 2 = 378
2 skulls= 72
2 power weapons =30
6 plasma pistols=90
Total=570

1 Defiler=150
Total for list=885

Way of the water warrior is probably the best overall thinking that I should employ; blast up his squads and prevent him from getting the charge with his units. But I am inexperienced, especially with our most hated of foes, so all your help will be INVALUABLE! Thank you all Brothers, most haste if possible!

I responded in your other post in tactica here : http://greyknights.forumotion.com/tactica-f1/behold-the-enemys-vile-1000-pt-list-to-aid-brothers-t960.htm#12781

as a sidenote, combat patrol is a special kind of game type with 1+troop, don't have to have an hq, no models with 3+ wounds or 2+ saves or all three armor values added to over 33 and 400 points or less.
