The last one I needed was a shiny snorlax and when we became forever friends I saw they had one, so I marked it as the one I wanted and sent the trade request.
I tried to tag some interesting stuff like costume shinies etc, but all they wanted in return was a normal Bouffalant (for me they are everywhere). I literally would have traded them anything I tagged (even an armored Mewtwo) and without any communication or going back and forth I was able to finally get a stupid shiny snorlax!!!
So thank you kind stranger, may you catch nothing but hundos for a week.
