Re: VDex Master Thread
If you're on Gaia, trades work in a similar way to Gaia trades, just with a few less steps. You send, they send back, you confirm, they confirm. Done.
For a trade back, you trade one way, then trade the other. It's just two trades, but you're trading back (hence the name) the same two pokemon to the person evolving.
If they send you a pokemon that is going to be evolved, wait until you trade it back again. That way, the proper owner gets credit for the evolution.
I just did it recently with a Graveler to get my Golem.
