All of the 920+ Pokemon in this save file are legal and will pass as legit. Every pokemon that can legally be obtained as a shiny has its shiny form in the save file, the other pokemon are there in non-shiny form. 90% of the Pokemon in this save file were hatched/captured in USUM meaning that they can be used on battlespot.
The first evolutions of almost all of the Pokemon will be level 1; the middle evolutions are often level 70. A majority of the final stage evolution pokemon are a smogon set.
I hope this save helps some people out there. All of the complete 806 pokemon sets I could find online were either completely riddled with illegal pokemon, or all of the pokemon only knew 1 move; that is not the case with this save file.
