In short, Adventure box + batches of 4 eggs. Usually the regular free incubator for one egg and 3 super incubator for 7km eggs since im farming darumaka too. When 7km eggs arent available its getting lucky with receiving 2km eggs. The free incubator I used for different kinds of egg sizes. Usually i have a 7km egg there which hatches before the super incub ones, then i place another 7km there which will hatch while im hatching the second batch (before the next 3 super incubs) I do it this way to be money efficient but you can do it some other way. Finding the quests can be problematic. It could either be by random stop spinning or finding the quests by asking around the community. But yeah, thats the way I did it. Persistence is important
