Castform is Pokédex #351, generation 3 (Hoenn). Snow-cloud Castform is a Basic Water Pokémon with 70 HP.
Snow-cloud Castform sits at 29/113 in Delta Species, position 29 of 114. Before it is 28 Slowking, and after it is 30 Starmie 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 Rare.
Temperamental Weather is listed as Poké-Power. Once during your turn (before your attack), you may search your deck for Castform, Rain Castform, or Sunny Castform and switch it with Snow-cloud Castform. (Any cards attached to Snow-cloud Castform, damage counters, Special Conditions, and effects on it are now on the new Pokémon.) Shuffle Snow-cloud Castform back into your deck. You can't use more than 1 Temperamental Weather Poké-Power each turn. The attack Holon Blizzard lists 20 damage. The cost is Water, Colorless. If Snow-cloud Castform has any Holon Energy cards attached to it, this attack does 10 damage to each of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Weakness is Metal ×2. Retreat cost is 2.
Castform (#351) has 21 other cards in the catalog. Those other cards are in 9 sets. The other printings with a release date run from 2004 to 2024. The earliest other card is Rain Castform 23/101 in Hidden Legends (2004). That card is named Rain Castform, while this one is Snow-cloud Castform. That card lists 60 HP, and this one lists 70 HP. Both list the rarity Rare. Sumiyoshi Kizuki illustrated that card, and Miki Tanaka illustrated this one. Retreat cost there is 1, and here it is 2. 5 other cards of Castform list a different HP.
The illustrator line reads Miki Tanaka. I count 192 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. Castform can fill a slot in Generation 3 binder (Hoenn). I still need this card.
