Why not go the way of Jagex, home sweet home, and do sidequests? For example, getting through the Sevii Islands wins a payout of an Eevee with a Jump Stone. Running through a particularly long route with no repels active and not encountering anything. Breeding a 5x31 Poke that has 30 IVs in the other stat. Stuff that is obtainable but requires some effort to get, so people who complain about being bored can have their cries of boredom delayed.
