For example, if I evolved Omanyte to Omastar in Pokemon Yellow and then transfer it to Pokemon Bank, will I have both National Pokedex entries for Omanyte and Omastar in my Pokemon Bank, even if I only have an Omastar now?
For exemple I trade alakazam for dratini My data will have dratini like own but not caught the trader will have alakazam own too but no caugh You will keep alakazam data and your trader will keep dratini data So nothing change you wil still have your pok by caugh and have new pok by own hope it will help
