As long as Wailord remains Asleep between turns, remove 1 damage counter from Wailord.

Great Encounters is a set in the Diamond & Pearl series. It was released on February 1, 2008. The printed size is 106, and the checklist is the same length. Wailord is 30/106, in position 30 of 106 on this checklist. Before it is 29 Unown [H], and after it is 31 Weezing. The listed rarity is Rare.
Wailord is a Stage 1 Water Pokémon with 200 HP. The card lists level 43. In the Pokédex this is Wailord (#321), generation 3 (Hoenn). The card says it evolves from Wailmer. In this catalog that name is Wailmer (#320).
Mitsuhiro Arita illustrated this card. The same name is on 721 other cards in the catalog.
Wailord (#321) has 23 other cards in the catalog. Those other cards are in 18 sets. The other printings with a release date run from 2003 to 2026. The earliest other card is Wailord 14/109 in Ruby & Sapphire (2003). That card lists 120 HP, and this one lists 200 HP. The rarity there is Rare Holo, and here it is Rare. Ken Sugimori illustrated that card, and Mitsuhiro Arita illustrated this one. 17 other cards of Wailord list a different HP.
Sleeping Pulse is listed as Poké-Body. As long as Wailord remains Asleep between turns, remove 1 damage counter from Wailord. The attack Sink Deep lists 60 damage. The cost is Water, Water, Water, Colorless. If Wailord has any damage counters on it, Wailord is now Asleep. Weakness is Lightning ×2. Retreat cost is 4. The flavor text reads "The biggest of all Pokémon. It can dive to a depth of almost 10,000 feet on only one breath."
I keep a set binder for Great Encounters, meant to hold every card of that set. This card is one slot in the Great Encounters set binder. A generation binder holds one card of each species. Wailord can fill a slot in Generation 3 binder (Hoenn). Themed lists that include this exact card are Mitsuhiro Arita cards. I still need this card.
