Dragonair is Pokédex #148, generation 1 (Kanto). Dragonair δ is a Stage 1 Lightning Pokémon with 70 HP. The card says it evolves from Dratini. In this catalog that name is Dratini (#147). The card lists Dragonite, Dragonite (#149) under evolves to.
Dragonair δ sits at 41/113 in Delta Species, position 41 of 114. Before it is 40 Ditto, and after it is 42 Dragonair δ. The set belongs to the EX series. It was released on October 31, 2005. The printed size is 113. This checklist is longer, at 114 cards. The listed rarity is Uncommon.

Dragonair (#148) has 28 other cards in the catalog. Those other cards are in 24 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Dragonair 18/102 in Base (1999). That card is named Dragonair, while this one is Dragonair δ. That card lists 80 HP, and this one lists 70 HP. The rarity there is Rare, and here it is Uncommon. Mitsuhiro Arita illustrated that card, and Hajime Kusajima illustrated this one. Retreat cost there is 2, and here it is 1. 19 other cards of Dragonair list a different HP.
The illustrator line reads Hajime Kusajima. I count 206 other cards in the catalog with that illustrator.
Delta Species set binder is where a full Delta Species set goes. This card fills one slot there. A generation binder holds one card of each species. Dragonair can fill a slot in Generation 1 binder (Kanto). Themed lists that include this exact card are Delta Species cards and Dratini, Dragonair, and Dragonite. I still need this card.
