Showdown: Khorne Daemonkin vs Iron Hands (March 10th)

Got a scheduled game coming up vs my friend. We have a pre-game routine on this we agree before game day in order to speed the game up and be able to finish it in time. Here are the list of things already pre-determined for Friday's evening game:

MIsson: The Scouring
Deployment Type: (My opponent decides on game day)
Objective placement: (I decide on game day)
My Opponent's Army: Iron Hands (Fist of Medusa) see army list below
My Army: Khorne Daemonkin (CAD/AD) see army list below
1st Turn: Coin Toss

So I'm looking for opinions and ideas on possible tactics to employ, things to look out for/be mindful of. Tips and Tricks that could help in this battle.
This is my regular opponent so we know eachother's playstyle fairly well. I am new to Khorne Daemonkin (this will be my 3rd game) and fumbled a lot of the rules on my first two games because of simply not knowing stuff, mostly things that would've worked to my benefit sadly. So i'm hoping to be air tight on the KDK rules this time around and looking for tips from the pros. I just bought this D-thrister and this will be my first game using him so i'd very much like to get him into combat and see what he can do.
