you have to get it via a wi-fi event, unfortunately it ended last year.
however if you have a friend who has it you may be able to "get via friend" on the mystery gift menu
you have to obtain the members card through mystery gift.(it may be possible trough AR.)
With the Japanese event or mystery gift
you get it through Nintendo event or mystery gift on Pokemon pearl platinum or diamond
You can get it through the Nintendo wifi.
You need to have Pokemon battle revoloution for wii and do mystery gift. What are they for?
no you can only get it by mystery gft
You have to go to a Nintendo event then they give you the member card. But, there hasn't been an event for that.
Mystery gift is not really an item. You get Mystery gift and on the main menu you can select it. You can have 3 wonder cards (a card you receive when there is a Pokemon event.) I hope this answered your question
its a mystery gift and if u dont no u find darkrai there
You can get the member card in diamond and pearl but the event for it in platinum is august 3rd to September 13th (you have to have wi-fi connection to do this)
first you must have 666666666666 darkrais than you can talk to the man in ##### and jubilife town than you get the members card
the event is over but you used to be able to get the members card which allows you to catch darkrai you can still get the members card with action replay
