How do you recatch Uxie?

I caught the other two legendaries and accidentally killed uzis without saving first.

(Don’t know if your still wondering about this), but once you k.o. a legendary, you can’t battle it again. The ability to rebattle legends yo defeat starts in Platinum.

From Bulbapedia

In all games, being defeated by a legendary Pokémon does not cause it to disappear. In all games in which roaming Pokémon exist, fleeingfrom them does not cause them to vanish; the game simply behaves thesame as if they were the ones to flee. In Pokémon FireRed,LeafGreen, and Emerald, if the player flees from a stationarylegendary Pokémon it will reappear upon leaving and re-entering theroom, unlike the previous games where a stationary legendary Pokémoncould only be encountered once. The game informs the player that “The<Pokémon> flew away!” In Pokémon Platinum, if the player defeats orflees from a stationary legendary Pokémon, it reappears after theplayer enters the Hall of Fame again. If the player defeats a roamingPokémon, the player must re-trigger the event which caused it to startroaming; for example, the player must talk to Professor Oak to cause alegendary bird to resume roaming. If the player flees from or defeatsOrigin Forme Giratina in the Distortion World, it will reappear inTurnback Cave in its Altered Forme, where it behaves in the same wayas all other stationary legendary Pokémon. This was extended to allstationary Pokémon (red Gyarados, Sudowoodo and Snorlax) in HeartGoldand SoulSilver. If Suicune is defeated or fled from, Eusine willcomment on this fact, and it will instead reappear at the BurnedTower, where it behaves in the same way as all other stationarylegendary Pokémon. If Ho-OhHG or LugiaSS is defeated or fled fromduring the storyline, the Kimono Girls will comment on this fact thenleave, but the two still behave like all stationary Pokémon. InPokémon Black and White, ReshiramB or ZekromW must be caught;defeating, fleeing or losing to the Pokémon does not cause it todisappear, and the story cannot be progressed until it is caught;instead, the player is warped back to the Pokémon League PokémonCenter to try again. However, if the player has a full party and PC,it is possible to progress without catching it. If this situationoccurs, it will instead appear at Dragonspiral Tower after defeatingTeam Plasma, where it behaves in the same way as all other stationarylegendary Pokémon. However, it will still not give any experiencepoints even in that situation.
