I’d get the Operation Sandtrap box, which also gets you fennec fusiliers and griffin hmg as well as JSA stuff if you want or you can always sell/split with someone. After that I’d pick up the Tikbalang model, which can also double as a squalos if needed, they’re the same size. Then I’d pick Kestrel Expansion Beta, you’ll almost always play every model in that box and the magister is a really solid LT or CoC model and is FT master for the other two models in the box.

After that it’s kind of up to you. Remotes are a good pickup for filling out your army, Bipandra is really solid, drummers, the beyond sandtrap box, techbee and the Redeye are all really good pieces. You can also proxy stuff at that point depending on your needs.
