What are the CP limits for each league?

Great League is capped at CP 1500 and Ultra League at CP 2500; Master League has no CP limit.

Why is a lower Attack IV often better in PvP?

In CP-capped leagues, a lower Attack IV often lets a Pokémon reach higher HP and Defense at the same CP, which can be stronger overall. Check each Pokémon's page for the best IVs per league.

How do Fast and Charged Moves work?

Fast Moves build energy and Charged Moves spend it. Each Pokémon's page shows recommended movesets and matchups for the meta.

What are these rankings based on?

Rankings come from head-to-head battle simulations for each league (based on PvPoke). Switching leagues shows only the Pokémon that are legal for that league.
