Help with Necron List 1k Points

Hey fellow Necron enjoyers,

I got into the Hobby at the end of last year and chose necrons as my first Faction.

I got the Combat Patrol and 500 Worlds Necron Battalion Box and a Skorpekh Lord.

I want to play casually against my friend and was wondering what i should get and how to structure my Army.

I'm still very new and am a bit overwhelmed by all the choices ^^

I'm open to pretty much anything but in general i want to go for a Destroyer Cult themed Army (big fan of em)
