I thought there was a trading OT, but I can't seem to find it...
But at any rate, I find myself needing 2 Cosmogs and a Type:Null or Silvally, in order to fill out a Living Dex when Bank hits. I'm about to start catching the Ultra Beasts, and it seems that there are some duplicates that you catch. In particular, 4 Pheromosas. Are those considered a good, fair trade? What if I aim for a specific nature, since Pheromosa is apparently great online?
EDIT: I suppose I should add I don't particularly care if the traded Pokemon were duplicated through PKhex or whatever, as long as they aren't straight *generated* by it.
