i discovered(i don`t if you already discovered it) a shiny pokemon is a combination of id,secret id and iv and when they match(i don`t how) in pid/iv generator you can generate a legit shini approved with legality checker
for example:
poke :id:65052 secret id:44336
iv:hp:4
atack:9
defense:31
speed:0
sp.atack:4
sp. defense:9
poke:any pokemon
and you will make a legit shiny pokemon try yourself and if you can investigate it
don`t post if you don`t try it
