Nicely said Zarc (*^▽^*) the whole community can try to help you just ask a question and we will try  to find the best answer for you d=====(￣▽￣*)b

Reborn is generally impossible if you haven't played competitive pokemon. I'm pretty sure at least 80-90% of the users on this site including me have good knowledge of competitive battling including best movesets, natures, EVs and general strategies on how to deal with a specific pokemon or a situation.

Obviously there are players who struggle because they don't have that knowledge. But that's what this forum is for. You could make a post asking for help for every single gym leader and constantly share your team. There'll always be people who'll help you get better.
