Further info: I’m trying to get a delta gallade for my elite four team, but I saved without checking the gender of my raltz. If someone has a male raltz they want to trade to me that would be awesome.
Judging from what I’m reading, you have to log online via the dexnav ingame, select trade and type in my username.
After that both of you have to press enter at the same time or the other person must press enter within a span of almost 2 minutes after the first one pressed enter. You need to have the pokemon to be traded in your party(preferably the 1st slot as sometimes you may be unable to move the cursor). Edit: This happens rarely these days.
