Lucky Pokémon

Lucky Pokémon are special Pokémon that are more likely to be stronger opponents in battle and require less Stardust to power up. Their minimum IV floor is 12/12/12.

Background
When trading Pokémon, there is a chance that Pokémon can become a Lucky Pokémon. The Stardust cost for powering it up will be reduced by 50%, which means they can reach a higher CP much faster than other Pokémon.

When traded, both Pokémon always either remain normal, or become lucky.

Appearance
Lucky Pokémon have a green label below their name, indicating that they are lucky. Their background also features shimmering effects on their Pokémon Profile and in the Pokédex. The number of each Lucky Pokémon a Trainer has obtained of one specific Pokémon is tracked in the Pokédex.

Trivia

 * Although Pokémon turn into Lucky Pokémon at random when traded, the longer a Pokémon has been held onto, the greater the chances that they will become Lucky Pokémon.
 * Before September, 2018, Lucky Pokémon had a minimum IV floor of 10/10/10.
 * The sparkly effect of a Lucky Pokémon on the Pokédex actually extends slightly into the entries immediately before and after it.
 * The background of Shadow Pokémon completely override that of Lucky Pokémon on the same Pokémon.
