lucky, for some people, they've already "completed" most of their islands and their breeding stations and hatcheries are either sitting idle, or pumping out monsters just to sell. there are a lot of players near the end of the game for whom collecting rares presents a new challenge, something to work towards. like shiny pokemon- only better, because of their increased income.

there is actually another benefit, for those who are not at the end of the game- you can breed a rare and an original monster together for a 100% chance of getting that monster. so if you want to breed a lot of quad-type monsters, all you need is one rare in that species and you can breed as many of them as you need.
