STANDARD CLAUSES
Sleep ClauseYou may only afflict one enemy pokemon with sleep at a time. You may sleep another only after the first wakes up or gets knocked out.
Note: Self-inflicted sleep (Rest) does not apply towards sleep clause, because the player willingly used it.
Evasion ClauseDon't use Double Team and Minimize.
Note: Abilities such as Sand Veil and Snow Cloak are fine, as those are conditional.
One-hit KO ClauseFissure, Guillotine, Horn Drill, and Sheer Cold don't belong in competitive play.
Species ClauseNo having two pokemon of the same species.
Note: You can feel free to have a pokemon and a lower evolution, such as a Porygon2 and a Porygon-Z, as they are different pokemon.
Hax Item ClauseBright Powder
Focus Band
King's Rock
Lax Incense
Lucky Punch
Quick Claw
Razor Claw
Razor Fang
Scope Lens
Stick
The above items don't belong in a competitive atmosphere, as they are luck-based and don't reflect player ability.
Self-KO ClauseMoves that KO the user or rely on the user being KOd (Destiny Bond, Explosion, Memento, etc.) are not allowed to be used if the would-be user is the last pokemon remaining.

OPTIONAL RULES
Duplicate Item ClauseSome choose to play under the circumstance that no two pokemon should carry the same hold item. Many reject this on account that Leftovers is often the best item for each of their pokemon.
Extended Game ClauseIt is optional, when playing with Ubers, to have to deal with Arceus, despite it not being obtainable without the use of a hacking device. So the Extended Game Clause allows the use of Arceus in Uber battles, as well as various berries not obtainable in-game.
