I try giving some away but other than that I releaseHope you don't mind me bumping into the conversation, but I had a question!
What do you do with all your extra MM Pokemon that didn't turn out shiny?
I was doing Dratini and got frustrated at only about 45 eggs. I am working on completing my Johto Pokedex now and have been using the GTS to get Pokemon I have to trade for. Those extra Dratini are coming in handy, they get snapped up almost every time.
What do you do with all your extras? Release them mostly?
