To get the National Pokedex, you must own at least 60 Pokemon. Then, beat the Elite Four. After doing so, go to Professor Oak's Lab and he will give you and your rival a National Pokedex.After defeating the elite four and your rival with 60 different kinds of pokemon registered in your pokedex you will earn the national dex upgrade from Professor Oak when you reload your file.
there are no specific Pokemon that can automatically beat the elite four. HOWEVER, ( i speak from experience) i beat the elite four with one Pokemon whitch was Samurott. i suggest using Samurott 2. hope i helped! :) - Raven
