Single post in Delta Pokemon Showcase!

i hope this is the place for this, i can't find any other threads about deltas besides the guide why do people want deltas? i know that's a subjective question, i'm literally asking those reading this: why do you want deltas? i've found a few through wonder trade or the shelter and they hold no special significance to me. a pokedex entry is considered complete without them, and while i can see it does start counting them if you have a delta of a species, it still counts as a complete entry. i'm thinking of evolving the ones i've found for the sake of that extra tick and then throwing them back into wonder trade. would that be a mistake? EDIT: this shinx is electric twice. i might keep this one actually that's hilarious
