A place where you could do the feature Pokemon has where you can trade but randomly so say I deposit a Pikachu for trade, I can put down what I want in return and only get that Pokemon. So in destinys case; I want the praxic fire so I'll trade a spare gjallahorn for it. Then when I go back to that person when the trades been done, I can get my praxic and a personal message from that person. Idk that's just me.
