Flashfire is a set in the XY series. It was released on May 7, 2014. The printed size is 106. This checklist is longer, at 110 cards. Walrein is 26/106, in position 26 of 110 on this checklist. Before it is 25 Sealeo, and after it is 27 Luvdisc. The listed rarity is Rare.
Walrein is a Stage 2 Water Pokémon with 150 HP. In the Pokédex this is Walrein (#365), generation 3 (Hoenn). The card says it evolves from Sealeo. In this catalog that name is Sealeo (#364).
Naoki Saito illustrated this card. The same name is on 270 other cards in the catalog.
Walrein (#365) has 12 other cards in the catalog. Those other cards are in 12 sets. The other printings with a release date run from 2004 to 2024. The earliest other card is Team Aqua's Walrein 6/95 in Team Magma vs Team Aqua (2004). That card is named Team Aqua's Walrein, while this one is Walrein. That card lists 120 HP, and this one lists 150 HP. The rarity there is Rare Holo, and here it is Rare. Ken Ikuji illustrated that card, and Naoki Saito illustrated this one. Retreat cost there is 2, and here it is 4. 9 other cards of Walrein list a different HP.
The attack Powder Snow lists 60 damage. The cost is Water, Colorless, Colorless. Your opponent's Active Pokémon is now Asleep. Big Tusk is another attack lists 120- damage. The cost is Water, Water, Colorless, Colorless. This attack does 120 damage minus 10 damage for each damage counter on this Pokémon. Weakness is Metal ×2. Retreat cost is 4. The flavor text reads "It shatters ice with its big tusks. Its thick blubber repels not only the cold, but also enemy attacks."
I keep a set binder for Flashfire, meant to hold every card of that set. This card is one slot in the Flashfire set binder. A generation binder holds one card of each species. Walrein can fill a slot in Generation 3 binder (Hoenn). I still need this card.
