Hmm...you know Powersaves?It's the current "Action Replay" on the 3ds,so yeah,it can inject some fake "events" on the games we have.That's why we have to be wary of those things. :/
But,on the good side,it can only generate a locked date,so if you try to use Powersaves,the event can only be generated on the date it was assigned/fixed to.And on a somewhat related topic about it,Powersaves(It can back up save files)+Poke Bank(store the desire pokes to be cloned)=Bulk cloning(revive the back up save,you now have 2 of the same pokemon,one on the revived save,the other on Poke Bank.)
Here's all the dates I got for these pokes.If you find/see someone offer these dates,you might wanna ask proof or something for them,that they are legit.Of course,not all of the events with these dates are hacks.
Spoiler:- Oh noez!A spoiler!:
Ok,I'll try to get back to you guys if I already got mine cloned
