Chaos Knight Army

Hi guys, Just getting into the hobby with limited funds. I really like chaos knights. So far I have 1 magnetized stalker and 1 magnetized brigand. I also have 2 unbuilt wardogs.

Could you guys tell me what an ideal and strong army composition is? Hopefully using what I already have but if not that ok. I just don’t know guns and enhancements and whether to buy big guys or not so a specific army list with weapons would be great. Again money is tight so although I like the hobby, I want to spend smart for what’s good right now.

Any help would be lovely. Thanks mates!
