>>48522367I've deleted thousands.
Not released, deleted.
I decided to breed a few shinies for myself and my friends in pokemon X. Along the way, I produced ~600 fennekin, ~500 eevee, and ~900 treecko.
The fastest way to get rid of that many breeding rejects? Transfer them to Bank, then to (my fresh copy of) Y. Then, delete the save on Y, and do it again.
No pretending they're frolicking through meadows, I put them in their own containment universe and then erased that universe.
