The best IVs for PvP are IVs which grant you the maximum amount of Defense and Stamina, and the least amount of Attack. Attack contributes to CP the most, which makes it not ideal for Trainer Battles, while high Stamina and Defense can get you through a lot more battles.

For Leagues with lower CP limits, such as the Great League, usually the best IVs you can have are 0 / 15 / 15, or something similar to that. The reasoning behind this is that we want to pack as much stats as possible in under 1500 CP, and low Attack IV allows us to do that.

For Ultra League, the situation is a bit different, as the CP cap is higher. Pokémon which top over 2500 CP will still prefer 0 / 15 / 15 and similar IVs, but Pokémon whose Max CP doesn't reach 2500 will prefer 15 / 15 / 15. Examples like Watchog whose Max CP is 2056 CP, should have 15 / 15 / 15 for Ultra League, while Scizor (3393 CP) should have 0 / 15 / 15 IVs which will result in 2499 CP, just under the cutoff point.

For Master League, where there is no CP cap, you want perfect Pokémon IVs - 15 / 15 / 15 - regardless of which Pokémon we are talking about.

In general, it is usually Pokémon with IVs you wouldn't use for Raids that are good for Trainer Battles. Also be aware that PvP IVs are important, but not as important as having correct moves and team composition.

Fast Attacks

NormalHidden Power Low quality3.002.67982s

Fast attacks create energy when used, which can later be used to fire off a Charge move. Unlike Charge attacks, Fast attacks don't have special status effects.

Ideally, for fast attacks you're looking for a move that has both high EPT and high DPT, for example Dragon Breath which has 4 DPT and 3 EPT. It's widely considered that 3 DPT and 3 EPT is the rough baseline for fast attacks in PvP.

  • PWR - Power, how much damage the move does
  • ENG - Energy, how much energy the move generates per use
  • CD - How long does it take to perform this move

Charge attacks cost energy to use, deal a large amount of damage, and some of them even have Special Effects that can change your or your Opponents stats.

Similar to Fast Attacks, some Charge attacks are strictly better than others. The main metric for comparing charge attacks is DPE (Damage per Energy), which describes how much damage you output per Energy point spent.
