At the moment i'm typing this, every Shelly run starts with gem grab and at 30 trophies they switch to (the better game mode for speedrunning) solo showdown. If u connect a Supercell ID to the account that you want to speedrun Shelly on , you get barley + a skin. This means that u can get barley to 30 trophies to unlock showdown, then u can do all your Shelly trophies on showdown what should be way faster. :)

@DemataPyro It actually isn't against the current rules, he doesn't mean during the run, he means before the run. Afaik There's nothing that prohibits gaining trophies with other brawler before the run even starts. Very good advice, I hadn't come up with it @BTVSnipeZ :)

@BTVSnipeZ Actually with that strat sub 10 would be possible. Great advice!

And thanks that you can win all your coins with barley before start your run as i said here https://www.speedrun.com/Brawl_Stars/thread/jbi7k
