Question: how to transfer pokemon from black to x without pokebank?
Answer: Possible to transfer without pokebank? Not unless you have a friend with Bank that is willing to let you use it. You would have to import them into your Black, trade them to someone else who has a copy of B/W/B2/W2 and a 3DS and have them import them for you. Then they could trade the Pokemon from their X/Y to your Y.
