Remote Trade with a Random Friend

I was doing a remote trade with a random friend, and they only had regular colored legendaries tagged. I picked Kyurem which luckily had a special move, but they just sent back Origin Dialga (shiny) and nothing else. So annoying... I usually leave multiple tags on because removing them for one person is a hassle, but that doesn't mean you can just pick and choose what you want. It would be one thing if you picked something comparable or selected multiple and tried for a shiny Origin Dialga knowing it might fail, but don't just send back a single specified Pokémon like that (). Anyway, it was a pain, but I removed a bunch of my remote trade tags... (›´-`‹ )
