you cant you have to do a event at a store or wifi give aways
,
I have Pokemon Black, and as far as i know you cannot catch event legendarys without an event (eg. Genocect, Zorua). You cannot catch some Pokemon on the game, but Pokemon White can, and White can't catch some Pokemon that you can catch on Pokemon White. Lol!
....you cant... but you can trade
Meloetta is an event Pokemon that is currently unavailable without hacking.
Only if you got the event.
you have to get the arceus event on mystery gift.
You can't without an event or action replay, gameshark,etc.
u can catch it by using balls but its a event Pokemon and the event might be comming soon
You'll have to catch them and the last 3 you need a Nintendo event.
No.
you can catch it when an event is going on.
You can't catch Mew in Platinum without the help of an Action Replay or going to Nintendo Sponsored Event, Sorry.
