>>29543471Start with wondertrading a lot while you're shitposting, then finish the regional dex by first catching everything you can and then evolving/breeding, then go for evolutions of mons you obtained wondertrading and finish by trying to trade for the lines you're missing.
Make sure you catch enough pokemon of a line to be able to evolve a few and avoid breeding, as it takes a bit longer. Stock up on money while you're training in for example the battle maison to buy tons of quick balls, and get yourself a false swiper.
Also, it'll take a ton of time, during which you might get bored and switch to playing other games, which is fine, never burn yourself out, you'll come back to it later.
Also note that between xy and oras you can complete the whole dex. That will probably not be the case in sm, so be prepared to go back to gen6 in case you need mons from there or trade with someone
