Data Sphere

Hi all
I've played few years ago and stopped but now want to return and also make demos with my current MMRF

Can someone advice what I should add to my existing collection

I have CA starter
+ Daturazi Witch Soldiers (Chain Rifle, Combi Rifle)
+Morat Infantry (HMG)
+The Shrouded (Sniper)
+Suryat (HMG)
+Morat Vanguard Infantry (Hacker)
+Void Operators (HMG)
+ Caskuda (TAG)
+Rasyat (Combi Rifle)

Now I'm refreshing my knowledge of rules but I still need ideas
What to add ? Should I make 2nd Army and etc?
So any advice would be helpful

Hungries (new style)
Drones
Vector Operator
Speculo Killer
Yaogat box + sniper
Ikadron Batroids

Pick your poison

Ikadron Batroids - already in my possession

Then go with the rest, everything I listed is stuff you're gonna have sooner or later anyway (unless you're single-sectorial or something).
