beat the elite 4 20 times then talk to the champ (or wally) and he'll take u to verse jirachi

none of that crap is true, u have to have bought some item at like target or something a long time ago, my friend has jurachi and i battled it, its level 100 and its not that hard to beat so dont bother tryin to get it, but, u have to have bough the thing a long time ago and then u program it in ur game and then u can find it in the wild at level 5.
