→Structure: You forgot sinnoh
In [[Alola]], due to the lack of Gyms in the region and the fact that its Pokémon League was only recently established, no specific conditions need to be met in order to enter its League Conference, and its winner was directly declared as the first-ever Champion of Alola.
Most Leagues use various types of fields during Pokémon battles. While the Vertress and Manalo Conferences uses only a standard dirt battlefield, every other Conference has held battles on various different battlefields, like icy, rocky, forested, grassy, and water to name a few. A standard rule for the Conferences with a myriad of battlefields, is that during the Full Battle stage in the tournament, once one side loses three Pokémon, there is a short break, during which a field change occurs.
