Full pokedex/living pokedex

[ReddyRaptor]

Finished my national pokedex a couple days ago, the fastest way I found was to get all the stage 1 pokemon, then go into the elite four with a level 100 pokemon (5 pokemon you want to level on your team). Keep doing this until you have every full evolution for every pokemon. At this point, breed using the mesuda method to complete your living dex (will give a chance to get a shiny while doing living dex). Then level any pokemon with the 3 stage evolutions to the second stage. Doing this, i finished my living dex in a week. 

Hope this helped
