Always pick the best Pokémon for battles!
Heres how it works:
1) On the "Select Opponent" screen, tap any of the 251 Pokémon that currently reside in the Pokémon Go Pokédex.
2) On the "Type Match" screen, see a list of the Pokémon with type advantage compared to the opponent you selected, sorted by most advantage to least.
3) Also on the "Type Match" screen, see a list of the Pokémon with type disadvantage compared to the opponent you selected, sorted by most disadvantage to least.
Type match results have color-coded borders that indicate relative type advantage and type disadvantage compared to the opponent you selected.
Tag your favorite Pokémon in the lollipop (Settings) menu to filter Type Match results by your favorite Pokémon.
