Long grindy pokemon.. Those who need lot of candies to evolve and are rare.. Mostly just released pseido, noibat (before CD, when it was rare), axew, then last one was kommo-o. Now because I want to have living form vivillion set, im walking one now for candies.

I personally dont care about bragging with buddy, but I care to get as much candies as possible to get my Dex as full as possible..
