Like all Pokémon games, the key to this game is getting all the Pokémon. Other than through transferring with friends, this is only able to be done by Spot Pass, the method of receiving automatic downloads through the Nintendo 3DS. There is however, a way you can increase the likelihood of the Pokémon you obtain from SpotPass being one which you desire. As such, this page will list the AR Markers for the Pokémon. Only use them if you wish to get that Pokémon. Do note, if you scan every Marker, it will render the increase likelihood useless.
