Best Naclstack IVs by league
| League | Rank 1 IV | Lv | CP | 15/15/15 |
|---|---|---|---|---|
| Little | not eligible — must be unevolved and able to evolve | |||
| Great (under cap) | 15/15/14 | 50 | 1457 | #1 |
| Ultra (under cap) | 15/15/14 | 50 | 1457 | #1 |
| Master | 15/15/14 | 50 | 1457 | #1 |
Naclstack 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.
Naclstack never reaches the 1,500 CP cap of Great League or the 2,500 CP cap of Ultra League: at level 50 it maxes out at CP 1457. In those leagues 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
IVs never change when a Pokémon evolves, so the spread you want depends on the league you are building for.

|---|---|---|---|
| Nacli | 0/15/15 CP 500 | 15/15/15 CP 1093 | 15/15/15 CP 1093 |
| Naclstack | ✕ | 15/15/14 CP 1457 | 15/15/14 CP 1457 |
| Garganacl | ✕ | 1/14/14 CP 1497 | 0/13/15 CP 2497 |

That answers a different question from the rest of this page. The IV ranks above tell you which Naclstack 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 Naclstack
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 Naclstack you already own, open the IV ranker and set its IVs.
