How do I get 30 different IDs?

It seems that in Castelia city there is a way to get a free choice scarf if you get 30 pokemon with different IDs. But i dont know if that means I can exchange 30 pokemon from another copy I have or do I need to trade one pokemon with 30 different people?

I am willing to spend money and the gems I have. I really want to get all the MHA cosmetics but i dont know for sure what is the most efficient way to get them. Either paying for the package in money and risking playing in the challenge for the uravity skin (will play with friends but could still lose). Or buy gems (a superpack or the ranked offer) or somewhere in between. Ive also considered just spending money cause i also want to buy the other Stranger things skins too that i misses last time. That's why i was wondering.

It's been since september that i last spent money, but since then i used to buy every single brawl pass since Kit came out. No holding back, just want to choose the most efficient purchase option for all available cosmetics
