Let's say my friend hacks his game and gives me a Cherish Ball - what catch rate would it have? Does it have a special effect? Would it be like a Poke Ball, Great Ball, Ultra Ball or Master Ball?
The Cherish Ball's catch rate is 1x. So, if you were to hack into the game, the Cherish Ball would just be like a Pokeball in all circumstances.
The Cherish Ball is there to simply mark it as a special Pokemon. :D
Hope I helped. :) Source
