Once you first start the game you are only aloud to bring in 20 pokemon. But there is a way to change this. First you send in all the pokemon you can in your game into My Pokemon Ranch, then save. Turn off your DS and go to the main menu. Change the day on your Calendar in your Wii to the next day, and you will be aloud to send in more pokemon. Just repeat this process as many times as you can to get 1000 pokemon in your Ranch in just one day.
