so i have been playing pokemon clover and i am getting absolutely filtered

every gym kicked and bossfight is kicking my ass, i got to the 7th gym before i was ultimately filtered and decided to quit and come back when i am better at pokemon

i was leveling up several pokemon and i made sure to keep the types and attacks diverse and have some utility instead of just 4 offensive moves or something, yet i keep getting destroyed

what should i do?
