may i asked where you checked it at?
No it is not hacked, Jirachi is a wondercard Pokemon and since the nature of the wondercard is random no IV spread is illegal.
-according to jubilee on smogon
I meant according to a competitive sense. Since it was RNGed it is possible to get that, however a hack checker would say it's hacked because for a jolly Jirachi to have the highest possible IV spread it would need to be one of the following:
23/31/31/31/31/31
31/30/31/31/31/31
31/31/26/31/31/31
31/31/31/6/31/31
31/31/31/31/29/31
31/31/31/31/31/24

Even more of a difference if it were to have HP Ground.
Im fine with that. It is a wonder card so its possible. Thats all i need to know
Allright, could you also see my thread for those pokes? since I don't see any Wants on your list
