Stelle Guides?

I am having trouble learning how to play Stelle. I did well 2 seasons ago and the first half of last season, but have been having troubles since. Are there any guides or good players on YT/Twitch that I can watch to learn her better?

Right now I'm not understanding her options. To me it has felt like you play the first gold+ large you get offered and hope you hinged your early game correctly.

I have tried start/stop early, tools, aerial gunner, burn lineups and I'm just not having much success. Any advice would be greatly appreciated!
