How to find a good Tapu Koko
The search-string generator builds a string you can paste into the search bar in Pokémon GO. It matches the CP, HP and appraisal stars of the top spreads above — pre-evolutions included — so you can sweep a whole storage box in one go.
To check a Tapu Koko you already own, open the IV ranker and set its IVs. It ranks every stage of the evolution line at once and shows the meta rank beside the IV rank.
