Best Cascoon IVs by league
| League | Rank 1 IV | Lv | CP | 15/15/15 |
|---|---|---|---|---|
| Little | not allowed — must be unevolved and able to evolve | |||
| Great (never hits the cap) | 15/15/15 | 50 | 626 | #1 |
| Ultra (never hits the cap) | 15/15/15 | 50 | 626 | #1 |
| Master | 15/15/15 | 50 | 626 | #1 |
Cascoon cannot enter Little League because it has already evolved. Little League only takes Pokémon that have not evolved yet and can still evolve, so the 500 CP cap is not the only rule.
Cascoon never reaches Great League's 1,500 CP cap and Ultra League's 2,500 CP cap: at level 50 it tops out at CP 626. Nothing is held back by the cap in those leagues, so the highest IVs simply win and 15/15/15 is best, exactly as in Master League.
Rank 1 IVs across the evolution line
IVs carry over when a Pokémon evolves, so pick the spread for the league you mean to play it in, not for the stage you caught it at.

How to find a good Cascoon
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 Cascoon 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.
