Replace the living dex with all perfect IV versions, making easy breeding fodder for whatever you want going forward. Make sure to give them 4 decent egg moves and good natures while you're at it.
Haha actually no just get into competitive play. That way you can discuss things with people and you aren't fighting against a cheating computer for BP.
>>28480269Really not too hard. Still, it's best to break it into chunks.
When XY came out I finished the Pokedex. I saved the majority of Pokemon leftover, but some were traded to friends who needed help or traded for other Pokemon I needed.
When ORAS came out, I took my mostly-done Dex and filled in the gaps. "Oh, I have Venusaur already, I'll breed two Bulbasaur and evolve them", etc.
Alternatively, you can just tackle one region's Pokedex at a time. Doing 10 Pokemon a day (very doable) will have you finishing in a little over two months.
>>28481830This is honestly the best reply but Pokemon clearly has grabbed OP by the balls and won't let go.
