* Wonder Mail in Explorers of Time: The game does not feature Wonder Mail. It was introduced in later Pokemon Mystery Dungeon games, like Explorers of Sky.
* Lucario's Availability: While Lucario is available in Explorers of Time, you cannot acquire it through Wonder Mail. You can recruit Lucario by:
* Finding its partner, Riolu: You can find Riolu in the Rare Pokemon Room in the Exploration Guild.
* Evolving Riolu: To evolve Riolu into Lucario, you need to level it up to level 30 during the day and have a high enough friendship level with it.
To clarify, there is no way to get Lucario via Wonder Mail in Pokemon Mystery Dungeon: Explorers of Time.
