These are the rules for challenging the frontier brains:
1: You have to have done one of the following: (a): Defeated the Pokémon League, or (b): Defeated every gym leader (We'll look at your Gym leader challenge posts if you are trying to lie to us)
2: You must follow all rules set out by the frontier brain in regards to the battle. Brains battle with their own preset rules, and they may change these rules at any time. Whether or not a brain decides to use Smogon competition rules or not is up to the individual brain.
3: There will be 8 different facility. Each of them have own different style. The style we have here is: Single, Double, Triple, Rotation, lvl 50s, lvl 100s, lvl 25s, baby cup, Sunny day, Rain dancing, Sandstorm, Trick room. If you want to be tested by one of this style, please ask our Elite fours or our Frontier Brains and tell them what style do you want to be tested for. Once they finish testing, they'll tell you if you'll be in or not
4: I will add or edit rules to help keep things balanced as time goes on.
