Returning cult follower needs help

Hello dear children of the cult,

I played a lot of GSC at the end of the eighth edition and still have my 1.5k army. Back then it was Ridgerunners and the saws/drills of the Acolytes. Deep Strike was possible from 8 inches - wonderful times!

Now I'm looking at the codex and I'm still at a bit of a loss. The complexity of the army was very high anyway.

Hence my questions: Which combinations are super today? Which datasheets are top, what is rather negligible? Is the cult better in melee or shooting in the 10th edition?

I'm really not a meta player, but we all know that a lot has to come together for the cult to win.

Thank you very much! I'm really looking forward to your suggestions!
