League Rules

General Rules

Teams and battle format

Battles are done with teams of 6 Pokémon. The challenged gym leader will determine the battle format (e.g. Single Battle, Double Battle, etc) and any special format rules.

Legality

All Pokémon must have legally available moves, items, and abilities available through normal game mechanics. As examples, Flareon can not learn Fly, the Fire Gem is not available in-game, and Magikarp can not have the Wonder Guard ability.

Pokémon clause

No repeat Pokémon. Alolan forms are considered different than their non-alolan counterparts.

Item clause

Multiple Pokémon cannot be holding the same exact item. Two Pokémon with leftovers is not acceptable, but two with different types of z-crystals is acceptable.

Sleep clause

You can only put one enemy Pokémon to sleep at a time, even if one of those sleeping Pokémon has been switched out.

No 1-Hit KO moves

You cannot have Guillotine, Fissure, Sheer Cold, or Horn Drill.

Evasion clause

No direct evasion increasing moves can be used, which only applies to Minimize and Double Team. Indirect effects are allowed, such as certain abilities such as Moody, items such as bright powder, or the random chance of Acupuncture.

Banned Pokémon

Gym Trainer Rules

A challenger may decide to represent a gym leader or type and earn points for that type through the tournament. All general rules still apply to these matches, but with the following caveats:

Typing

All Pokémon used must be of your gym's typing as it enters the field, without the use of an item.

Megas

All Pokémon used must be of your gym's typing before mega evolving.

Z-Crystals

Initially, only the z-crystal you can use is that of your type. As you earn gym points, you unlock the z-crystals of the Gym Leaders you have defeated.

Signature Z-Crystals

An exception to the above rule is when a Pokémon in use with two types has a signature z-move. As examples, a ghost-type Gym Trainer can use a Mimikyu with Mimikium-Z, even though Let's Snuggle Forever is a fairy-type move. A fire-type Gym Trainer can use an Incineroar with Incinium-Z, even though Malicious Moonsault is a dark-type move. Ditto and Smeargle can only use such Z-Crystals if the Gym Leader of the crystal's type has been defeated.

Points and Badges

You can use a Gym Trainer team that follows the above rules to earn a badge and a gym point in one battle; or you can use a different team to earn the badge but not the gym point.


Challengers' Tournament Rules

For the finale of a season, a tournament between league challengers take place. The tournament will take place in the Ultra Sun or Ultra Moon versions. During this tournament, all General Rules must be followed. The tournament is single-elimination, 6 vs 6 single battles. Placement within the bracket is determined by number of badges earned, and at least one badge is required to enter. Each challenger must use a single team through the entire tournament.
