>Pal Park uses a special type of Poké Ball known as a Park Ball, which has a 100% capture rate, much like the Master Ball. -Bulbapedia
It says it works like a Master Ball, what if you were to hack it into your bag? Would it work the same way as it does in Pal Park? Can you even hack it into your bag?
Yes, it will basically become a Master Ball since it has that 100% Catch Rate.
Source: Tested with Dream Balls which is essentially the same thing.
