Legends Awakened is a set in the Diamond & Pearl series. It was released on 1 August 2008. The printed size is 146, and the checklist is the same length. Uxie LV.X is 146/146, in position 146 of 146 on this checklist. The card before it is 145 Rhyperior LV.X. The listed rarity is Rare Holo LV.X.
Uxie LV.X is a Level-Up Psychic Pokémon with 90 HP. The card lists level X. In the Pokédex this is Uxie (#480), generation 4 (Sinnoh). The card says it evolves from Uxie. In this catalog that name is Uxie (#480).
Shizurow illustrated this card. The same name is on 79 other cards in the catalog.
Uxie (#480) has 8 other cards in the catalog. Those other cards are in 8 sets. The other printings with a release date run from 2007 to 2026. The earliest other card is Uxie 18/123 in Mysterious Treasures (2007). That card is named Uxie, while this one is Uxie LV.X. That card lists 60 HP, and this one lists 90 HP. The rarity there is Rare Holo, and here it is Rare Holo LV.X. Ryo Ueda illustrated that card, and Shizurow illustrated this one. 8 other cards of Uxie list a different HP.
Trade Off is listed as Poké-Power. Once during your turn (before your attack), you may look at the top 2 cards of your deck, choose 1 of them, and put it into your hand. Put the other card on the bottom of your deck. This power can't be used if Uxie is affected by a Special Condition. You can't use more than 1 Trade Off Poké-Power each turn. The attack Zen Blade lists 60 damage. The cost is Colorless, Colorless. Uxie can't use Zen Blade during your next turn. Weakness is Psychic ×2. Retreat cost is 1. The card text says: Put this card onto your Active Uxie. Uxie LV.X can use any attack, Poké-Power, or Poké-Body from its previous level.
I keep a set binder for Legends Awakened, meant to hold every card of that set. This card is one slot in the Legends Awakened set binder. A generation binder holds one card of each species. Uxie can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Lake guardians and Pokémon LV.X. I still need this card.
