It is definitely dependent on what starter you chose, I selected Ralts and the Result was Espeon I'm happy with the results.
I have a ton of Ice Stones, All eeveelutions in my party except Leafeon, Glaceon was my most used/ stongest, Flareon my least, had few water stones, if only i had used my
familys email i could be 100% sure it was based on selection of starter.
Unfortunately i can't participate in the "raffle" to get items since i dont live in japan, sucks, oh well i just wanted a special eeveelution.
As for the sav file, i'm not really familiar with the whole thing, if i figure it out by the start of the next phase i'll try to help out.
