The cult just invited a new adept what would you reccomend for him ?

Hello hive mind of the great four arms emperor, I have a big challenge for myself this month. I’ll build and paint a 2000 points genestealer cult army

I bought two patrol and some atalan jackals, what would you reccomend to keep expanding ? Budget is fine and i love every single model !

Is a baneblade a good idea tho ? I have a stupid conversion idea…
