you get a wonder card or a mystery gift
at a Nintendo event (which no longer happens) or by trading with another game
just about every single Pokemon-based website, especially Pokemon.com, will tell you the times of a Nintendo event. Right now is arceus at toys r us.
Wherever Nintendo is at for said event
a Nintendo event is a real life event that you go to get a item for a game
yes but you dont know when the event happens
So far, there is no Nintendo event to get Arceus for your DS or DSi.
an action replay is a device that gives you cheats while you are playing the game. a Pokemon event is something that happens when you have a certain Pokemon with you and it shows a short clip
the only way to get the AZURE FLUTE not azelf flute ( I've used an action replay and got it) you have to go to Nintendo world during a live event which only happens one week a year
The time and location of Nintendo events will be announced by Nintendo.
its from a Nintendo event not a mystery gift and you get it from a event hosted by Nintendo
