Instructions
Insert "Pokemon SoulSilver" into the top slot of your Nintendo DS. Turn on your DS and start "Pokemon SoulSilver." At the game's main menu, click on "Mystery Gift" and a new menu will appear. At first, you will only see one option, "Receive Gift," on the Mystery Gift menu. Once you get a Wonder Card, a second option will show up: "Check Card." Select the first option by highlighting it and pressing "A."
Highlight the "Get From a Friend" option and press "A" to select it to obtain a Wonder Card if you missed an event. Players can trade certain Wonder Cards to other players, so a player can get the Event Pokemon even if she didn't attend a particular event. This option utilizes the DS's wireless capabilities.
Select the "Get From Wireless" option by pressing "A" after highlighting it. You will use this option whenever you go to a Pokemon Event located at a Toys"R"Us or another location. You can use the Wonder Card to obtain rare Pokemon, items or Poketch applications
Highlight the "Get From Wi-Fi" option and press "A" whenever Nintendo puts up a Wonder Card. "Pokemon SoulSilver" will connect with Internet servers to get Wonder Cards via Wi-Fi. You must have Wi-Fi connectivity if you want to use this option.
Leave the "Mystery Gift" menu and start the game. Travel to any of the Kanto and Johto Poke Marts and talk to the delivery man standing in front of the counter. He will give you the Wonder Card.
