I expect hate for this but whatever.
Before the end of my Black 2 I was able to use an app called pokébuilder (pictured) that I used to get all the starter Pokémon (not with full stats or anything, just basic for breeding to make them myself), and to get the legendaries for my dex.
Now this app hasn't had an update to work on X/Y or AS/OR so was wondering if anyone knew of alternative means to get otherwise unobtainable Pokémon?
