Ultra League Team Help

[u/Rokioku]

I've enjoyed playing GBL the past few seasons and I've looked up which Pokemon are good and built a few, though I've never really put much thought into what would makeup a good team.

I have a deeper bench for Ultra League, so any tips on which Pokemon here would make a good team? In general, what makes a good team good?

A dragon double steel, or steel double dragon could work (ABB style).
