There needs to be a world machine that lets you pick what kinds of protectors you want in your world, and to turn pandoras and spawners off.
Brass>Protector size limits
Diamond> Pandora on/off
Onyx> Spawner size limits and on/off
However you would only be able to use it in a world that didn't have any protectors, pandoras, or spawners yet.
You could make money off of it, and it would solve the problem of having triggered Deepworld'igans.
