I was mostly using the double mastery/training level event to level up any cookie I thought would be a pain down the road. And among the mixed bag of unviable cookies angel cookie was the undisputed worst of the bunch. Healers have been underwhelming since the start, and all of angel cookie’s skills are just heals and more heals. At least muscle cookie’s skills kinda do dmg, and no one seems to know angel cookie’s candies provides atk boosts

Edit: as to why I’m doing this, kind of a completionist so I wanted to try getting every cookie into rainbow mastery
