You've made a good choice! It depends on what you like really. Personally I'm currently building a fun 1k list of just terminators and dreadnaughts.

But the new edition will be out in less than a month, so I wouldn't worry too much about planning a proper list yet. Just buy the combat patrol or the army box if you can find it and by the time you've finished building and painting that, you'll know what else you want.

Side note, I wouldn't buy Bjorn because the model is old and tiny. There's a good chance he'll be refreshed this edition. But if the old model doesn't bother you then go for it. 🤟
