>>26595147First off, for unevolved mons in your dex that you need, you can usually get away with putting up a 5iv level 1 mon on GTS. Back when I started the shiny charm wasn't even possible to get in gen 6 yet.
Second, just run around the region and catch one of everything you need. For example, for Scatterbug's line, catch three of them, and evolve one to Spewpa and another to Vivillon. This won't take long at all AND it's a step towards a living dex. If you have a living dex, when a new gen comes out, all you worry about are the new pokemon. There are people that would be more than willing to hand you a breeject just for your dex.
As for the shiny charm, I've gotten an Eevee and Trapinch in W2. In Y i've gotten a Chespin/2 Woopers/2 Mareeps/Zigzagoon off the top of my head, not counting the friend safari. In AS since the charm boosts dexnav rates I've gotten 2 Eevees/Zigzagoon/Sewaddle/Porygon/Gulpin/Spinda/Latios/Regirock/Registeel/Zekrom, not counting chain fishing
