This is Assuming Raven Guard and while not super competitive (because Primaris aren't)) it would do you well in pick up games.
Captain and Lieutenant stick to the Hellblasters with their Auras, scouts screen. Inceptors deep strike and delete your enemies biggest threat (fun fact: Plasma Inceptors will usually kill a Daemon Prince in one round of shooting!). Aggressors are there mostly because you said Raven Guard, use the strat on them to deploy them next to your enemy screens and fill them full of lead!
