Like in the movie, Jirachi will grant your wish, but the wish has a consequence! The person above you will make a wish, and you must create a consequence from that wish. (Example would be how Jirachi materialized chips and snacks, but the chips and snacks came from someone’s shop, which was morally wrong by stealing.) You can get as creative as you want with your wishes and corruptions, I’ll start it off with something simple;
The server fixes itself but with its newfound sentience it rebels against the humans and starts the machine uprising! Humanity is doomed! But thats ok… soon the pokemon shall inherit the earth!
I wish for a hat that is made out of cotton candy!
