Whose Rules? Pokemon X and Y’s Rules In Offical Pokemon Tournaments

For those who don't know among League of Legends, Halo, Call of Duty, Fighting games etc. Pokémon is also played in a competitive setting especially now that the Pokémon Video Game and Trading Card Game Winter Regional Championships are finally upon us, and they're strictly X & Y. What this means is that according to the official rules players cannot use Pokémon obtained outside of the Pokémon found in Pokémon X and Y that also means, no friends safari, no Pokémon Black/White.
