I doubt unless they have good shinies to trade people would willingly trade over their DLC mon either shinies or perfect IV mon, it's bad now with stuff like Shiny Gigantamax or IV perfect Raids, i've seen a fair few peeps try n charge cash for it, so i'd imagine DLC mon would be in similar vein...
Definately gonna get them aside from the 200 pokemone being supposedly added i quite enjoyed how the Wild Area functioned and having two more maps like it makes me happy
Though anyone else notice that Calyrex seems a lil similar to Digimon Tamers Calumon?
