I have a 2ds and would like to buy a flash card for it. I want to be able to transfer Pokémon from gen v to gen vi roms and then to a gen vii room and then ultimately to a legit gen vii game all through pokebank. First, it's this possible with a flash card? If so, what's the cheapest flash card that can do this? If not, how far can I get in this plan with a flash card? Sorry if it's a dumb question, but I'm getting back into the ds and haven't had a flash card since my ds lite. Thanks.
