Smogon:
> Evasion Clause - A Pokemon may not have the moves Double Team or Minimize in its moveset.
Generally, this rule will be automatically enforced in simulator play. In Wi-Fi play, a player is considered to have broken the clause when a Pokemon is revealed to have been brought into the battle with a banned move.
This is due to a Pokemon using it so much that it becomes near-impossible to hit unless the opponent has Keen Eye.
However, this is Smogon.
In battles that were challenged to you by passerby and acquaintances anything goes. If a trainer named Miror B challenges you and has 6 Ludicolo, even though that's breaking the species clause, it is still okay in non-competitive, Wi-Fi play.
