AbilityWater Immunity
You can't attach Water Energy cards from your hand to Articuno.

Articuno is Pokédex #144, generation 1 (Kanto). Articuno is a Basic Water Pokémon with 80 HP.
Articuno sits at 4/144 in Skyridge, position 4 of 182. Before it is 3 Arcanine, and after it is 5 Beedrill. The set belongs to the E-Card series. It was released on May 12, 2003. The printed size is 144. This checklist is longer, at 182 cards. The listed rarity is Rare.
Water Immunity is listed as Poké-Body. You can't attach Water Energy cards from your hand to Articuno. The attack Freeze Solid lists 10 damage. The cost is Colorless. If there are any Water Energy cards in your discard pile, flip a coin. If heads, attach 1 of them to Articuno. Ice Cyclone is another attack lists 50 damage. The cost is Water, Water, Colorless, Colorless. Flip a coin. If heads, this attack does 10 damage to each of your opponent's Benched Pokémon. If tails, this attack does 10 damage to each of your Pokémon in play. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Metal ×2. Resistance is Fighting -30. Retreat cost is 2.
Articuno (#144) has 45 other cards in the catalog. Those other cards are in 30 sets. The other printings with a release date run from 1999 to 2026. The earliest other card is Articuno 22/53 in Wizards Black Star Promos (1999). That card lists 70 HP, and this one lists 80 HP. The rarity there is Promo, and here it is Rare. Toshinao Aoki illustrated that card, and Hajime Kusajima illustrated this one. Retreat cost there is 1, and here it is 2. 43 other cards of Articuno list a different HP.
The illustrator line reads Hajime Kusajima. I count 206 other cards in the catalog with that illustrator.
Skyridge set binder is where a full Skyridge set goes. This card fills one slot there. A generation binder holds one card of each species. Articuno can fill a slot in Generation 1 binder (Kanto). I still need this card.
