beautiful people of the forum, I would like you to put the mysterious exchange system in the game, the system would work as follows:
on the pc it opened a new option "mysterious exchange" and when selecting that section it would ask you to put a pokemon and the way to receive pokemon to make it fair would be: you put a pokemon and you have to choose which ivs you want it to have, you can ask a pokemon that has the same amount of ivs in speed and attack but the others that you did not select do not matter, you can also ask for a pokemon with exactly the same ivs as yours (they also open the options that they are of the same level or of the same egg group, that's optional)
Sorry if you don't understand something, I'm Spanish and I wrote this with the translator?
