I kinda like that ability. I always felt kinda bad for those guys who stuck with non-dragon typings
Agreed, but it's safe too say that old pokemons will return unlike gen 5. If they would continue that from gen 5, they would never show old pokes as it would be the opposite of their fresh start marketing. So i think it's pretty safe too say old pokes will be found pre-national dex, doesn;t have to mean it have too be many. I just hope magikarp can be caught in early game!
