Basically what I had in mind is that you complete the Pokemon Ruby Game and pick up EV Reducing Berries as you go along because there is a lot of them, then give them to a Pokemon and migrate them to Heart Gold/ Soul Silver then migrate them to Black/ White 2 and you've got a load of EV Reducing Berries.
The reason I asked this question is because in Pokemon Ruby the berries are only used for Pokeblock Ingredients AND NOT ACTUALLY FOR REDUCING EV'S. As the EV Reducing Berries were not invented until Pokemon Emerald. Because of this there is a lot of them that can by regrown.
Because they could not actually reduce a Pokemon's EV's in Ruby I'm wondering If they could reduce a Pokemon's EV's in a more modern game if given to a Pokemon and then migrated over as the software has been updated on the more modern games for the Berries to reduce a Pokemon EV's.
I speculated that this could possibly work and you could have access to more EV Reducing Berries than you can on Black/ White 2 because as I'm aware I think you can only get the Berries after defeating The Black Tower/ White Treehollow and even then you only get one.
One Berry for all that effort seriously I wouldn't have even bothered if you didn't get a Shiny Gible/ Dratini afterwards.
Does anyone see a flawed in this plan? I mean unlimited EV Reducing Berries because you can grow them and then transfer them over to a game where they actually reduce EV's unlike in Ruby where they can only be used as ingredients for Pokeblock.
