Single post in Gym Forum Rules

I'm wondering, are we allowed to put things in our gyms that make them somewhat like the Gyms from Pokemon games? I was thinking of either using the Roulette feature from the Battle Arcade or a Pokemon Quiz like the ones from Hearthome and Lumiouse City gyms Also, you said we can make our own rules in our gym, as long as they don't make it impossible to defeat the gym, does that include a rule about what type of Pokemon the challenger can use? I don't mean like legendaries or Megas, I mean making challengers using Poison-type Pokemon in a Steel-type Gym
