Known as "The Being of Knowledge." It is said that it can wipe out the memory of those who see its eyes.
Uxie was one of the most widely-used Pokémon in the previous Modified Format, due to its Set Up ability. Set Up's ability to draw up to seven cards when Uxie is played from the hand, in combination with its Psychic Restore attack to compensate for a poor Uxie start, made Uxie a staple drawing card in many decks. Because it was such a useful card, Uxie's price and trade value skyrocketed far above that of most normal rares.
