I've got event mon in cherish balls most of mine are in pretty standard balls though. I'd have to look I may have some hidden abilities though. I found an eevee in a beast ball. After checking all my mon I have tons of hidden abilities only that eevee stands out as a unique ball though.HA is just an informal abbvreviation for Hidden Ability. I have a complete dex currently, mostly i'm looking for stuff like starters in beastball or apricorn balls, fossils in non basic balls (i am looking for kabuto in diveball for example) and the like. I would not ask you for a legendary pokemon in exchange for meltan since meltan is really easy to obtain for me, so if you can offer some rare ball mon that is more than good.
