Floatzel GL LV.X is a Level-Up SP Water Pokémon with 100 HP. The card lists level X. In the Pokédex this is Floatzel (#419), generation 4 (Sinnoh). The card says it evolves from Floatzel GL. In this catalog that name is Floatzel (#419).
Mitsuhiro Arita illustrated this card. The same name is on 721 other cards in the catalog.
Floatzel (#419) has 14 other cards in the catalog. Those other cards are in 14 sets. The other printings with a release date run from 2007 to 2025. The earliest other card is Floatzel 26/130 in Diamond & Pearl (2007). That card is named Floatzel, while this one is Floatzel GL LV.X. That card lists 90 HP, and this one lists 100 HP. The rarity there is Rare, and here it is Rare Holo LV.X. Masahiko Ishii illustrated that card, and Mitsuhiro Arita illustrated this one. 12 other cards of Floatzel list a different HP.
Water Rescue is listed as Poké-Body. Whenever any of your Water Pokémon (excluding any Floatzel GL) is Knocked Out by damage from your opponent's attack, you may put that Pokémon and all cards that were attached to it from your discard pile into your hand. The attack Energy Cyclone lists 20× damage. The cost is Water, Water. Choose as many Energy cards from your hand as you like and show them to your opponent. This attack does 20 damage times the number of Energy cards you chose. Put those Energy cards on top of your deck. Shuffle your deck afterward. Weakness is Lightning ×2. The card text says: Put this card onto your Active Floatzel GL. Floatzel GL LV.X can use any attack, Poké-Power, or Poké-Body from its previous level.
I keep a set binder for Rising Rivals, meant to hold every card of that set. This card is one slot in the Rising Rivals set binder. A generation binder holds one card of each species. Floatzel can fill a slot in Generation 4 binder (Sinnoh). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
