AttackTake Down
Wailord does 20 damage to itself.

Ruby & Sapphire is a set in the EX series. It was released on 1 July 2003. The printed size is 109, and the checklist is the same length. Wailord is 14/109, in position 14 of 109 on this checklist. Before it is 13 Swampert, and after it is 15 Blaziken. The listed rarity is Rare Holo.
Wailord is a Stage 1 Water Pokémon with 120 HP. 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).
Ken Sugimori illustrated this card. The same name is on 1,112 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 ex 100/100 in Sandstorm (2003). That card is named Wailord ex, while this one is Wailord. That card lists 200 HP, and this one lists 120 HP. The rarity there is Rare Holo EX, and here it is Rare Holo. Ryo Ueda illustrated that card, and Ken Sugimori illustrated this one. Retreat cost there is 5, and here it is 4. 22 other cards of Wailord list a different HP.
The attack Take Down lists 50 damage. The cost is Colorless, Colorless, Colorless. Wailord does 20 damage to itself. Surf is another attack lists 70 damage. The cost is Water, Water, Water, Colorless, Colorless. Weakness is Lightning ×2. Retreat cost is 4.
I keep a set binder for Ruby & Sapphire, meant to hold every card of that set. This card is one slot in the Ruby & Sapphire set binder. A generation binder holds one card of each species. Wailord can fill a slot in Generation 3 binder (Hoenn). I still need this card.
