I'm so sorry. I'm still considerably new to the 3ds Pokemon games. I played all the gameboy ones and ds ones, left for gen 6 and 7, came back for 8.
I need the trade evos for my dex, and I want to complete the dex as legitimately as possible. I was thinking of offering my legendaries on the GTS for the ones I need but.... I can't find it. Is it even in the Gen 7 Games? If so, where?
How do I get my trade evolutions by myself?
