Best Duosion IVs by league
| League | Rank 1 IV | Lv | CP | 15/15/15 |
|---|---|---|---|---|
| Little | not eligible — must be unevolved and able to evolve | |||
| Great | 0/15/13 | 28 | 1497 | #385 |
| Ultra (under cap) | 15/15/15 | 50 | 2282 | #1 |
| Master | 15/15/15 | 50 | 2282 | #1 |
Duosion cannot enter Little League, because it has already evolved. The format takes only Pokémon that have not evolved yet and still have an evolution ahead of them — the 500 CP cap is not the only rule.
Duosion never reaches the 2,500 CP cap of Ultra League: at level 50 it maxes out at CP 2282. In that league nothing is held back by the cap, so the highest IVs simply win and 15/15/15 is best — the same as in Master League.

Rank 1 IVs across the evolution line

That answers a different question from the rest of this page. The IV ranks above tell you which Duosion to build; this tells you whether it is worth building at all. Rankings and movesets come from PvPoke, who run the battle simulation behind them, and change as the meta does.
How to find a good Duosion
The search-string generator builds a string you can paste into the search bar in Pokémon GO. It finds catches whose CP, HP and appraisal stars match the top IV spreads above, including pre-evolutions, so you can check a whole storage box in one go.
To check a Duosion you already own, open the IV ranker and set its IVs.
