The Deployment:
I set my shooty guys around Zhufor and the melee guys on the edge of the deployment zone.
Grey Knights set Celestine and surround her with Razorbacks, rest of the army in reserves.
I was supposed to start but my adversary stole the initiative.

Grey Knights Turn 1: 
Celestine flew 24" directly towards the batteries and managed to engage them. All the guys got out of the transports and killed the Scorpion which exploded and wounded the Blood Slaughterers. Grey Knights also got a few wounds on the other batteries and the Contemptor Dreadnought.

Skulltakers Turn 1:
Green Blood Slaughterer assaulted a squad and killed it, the other one managed only to kill 3 out of 5. Predator killed Celestine, and batteries took out one squad and 3 more from another.

Grey Knights Turn 2:
Both Blood Slaughterers die and the Contemptor Dreadnought is reduced to 2 wounds. Celestine charges the Predator and Zhufor but gets her ass kicked.

Skulltakers Turn 2:
Decimator burns a squad of marines. Batteries and Dreadnought kill a few more marines. Zhufor kills Celestine in combat.

Grey Knights Turn 3:
Decimator and Dreadnought die. Draigo and 2 marines assault Zhufor and kill him.

I conceded since didn't have any units left to use.

Celestine is really annoying being able to move 24" and loosing first turn was a game changer.
