1. First on your pkmn x version put up a shitty Pokémon like caterpie on the gts and ask for the species of said shiny pkmn. Make sure to put something recognizable in the message. Then save and remove the game.
2. Put in the pkmn OR game (the one with the shiny pkmn) go on the gts, and look for your own pkmn. Once you find it, trade yourself the pkmn.
3. To get it back put the shitty pkmn back on the gts and ask for the EVOLVED form of the shiny the pkmn you traded. Don't forget to leave a recognizable message.
4. After saving and removing pkmn OR, Insert the pkmn x game and turn it on. Once you get to the gts find the shitty pkmn you left there and trade back your newly evolved shiny pkmn.
This only works if you have 2 Gen 6 games. If you don't, there's always eviolite.
