I own both Pokemon Y and Alpha Sapphire. My goal is to use AS mostly to catch Pokémon I can't get on Y, and then transferring them to there using the Pokébank. The friend safari in Y is also a huge help to be able to get types I couldn't get otherwise.
Going from these facts, and the assumption I could get any Pokémon family available in the friend safari through codes and then breeding them, for which ones do I still have to trade?
