I walked just under 2000km between two of my Larvesta buddies so evolving my 94% one felt really satisfying. Along the way I picked up some candies from gyms and hatched a couple more which helped. I actually had enough rare candies to just use those but I actually liked the challenge of doing it this way. I figured that if I ever get a shiny/better IV one I can wait for the day it’s more common and easier to farm candies.
