Before battling your opponent, make sure to follow these rules:

  • All matches must be played on Pokemon Showdown! or Pokemon Online (if you are playing ADV).
  • All battles will be standard XY OU, BW2 OU, DPP OU or ADV OU.
  • You are not allowed to use Pokémon, abilities, ability combinations, moves, or items classified as "Uber."
  • All tiers are based on Smogon tiers. The current status of the appropriate standard ladder will function as the prevailing tier list.
  • Species Clause: A player cannot have two of the same Pokémon on their team. For example, a player cannot have two Koffing on his or her team.
  • Sleep Clause: A player cannot put two or more different opposing Pokémon to sleep using attacks that induce sleep to opposing Pokémon.
  • Evasion Clause: A player cannot increase their Pokémon's evasion stat with a move that specifically increases evasion. Items or indirect boosts do not break this clause.
  • OHKO Clause: Players cannot use moves that have a chance of instantly KO opposing Pokémon. For example, Horn Drill is an illegal move to have on a Pokémon's move set.
  • Wi-Fi Clause: Team preview must be turned on when playing BW2 OU and XY OU.
  • Moody Clause: No Pokémon using the Moody ability may be used.
  • If a battle ends in a draw, a rematch will occur with the option for both players to change teams.
  • Timed Battle must be enabled.

Violating these rules will earn a loss for your team and may result in you being banned from all future World Cups.

Please note, these are the rules for actual battle: How to schedule matches and contact your opponent are specified in the current World Cup of Pokémon thread, in the Tournaments Forum.
