Electric gym
physick gym
bug gym
Dark gym
Fire gym
Dragon gym
and just my idea why we don't have shiny gym where we need to have 1 shiny pokemon to join it
there's no shiny gym because not everyone has a shiny and that isnt fair to either raise the money, catch something rare (or box), or try to shiny hunt
