Hold L and R on the screen that says bag, pokedex, Pokemon etc... Go into the bag. You should have 493 masterballs (not always in the right place so check your whole bag, mine were in items) used as numbers of the Pokemon in the pokedex. Just deposit the number of masterballs to get the number of the Pokemon in the pokedex that you want. For example: If you want Mew, you have 493 balls. Toss 342 of them to get 151, Mew's number in the pokedex. Just hold L while walking around in the wild to encounter that pokemon.
