Guardians Rising is a set in the Sun & Moon series. It was released on 5 May 2017. The printed size is 145. This checklist is longer, at 180 cards. Decidueye-GX is 146/145, in position 156 of 180 on this checklist. Before it is 145 Mallow, and after it is 147 Incineroar-GX. The collector number is above the printed set size of 145. The listed rarity is Rare Rainbow.
Decidueye-GX is a Stage 2 GX Grass Pokémon with 240 HP. In the Pokédex this is Decidueye (#724), generation 7 (Alola). The card says it evolves from Dartrix. In this catalog that name is Dartrix (#723).
5ban Graphics illustrated this card. The same name is on 1,629 other cards in the catalog.
Decidueye (#724) has 20 other cards in the catalog. Those other cards are in 12 sets. The other printings with a release date run from 2017 to 2026. The earliest other card is Decidueye 11/149 in Sun & Moon (2017). That card is named Decidueye, while this one is Decidueye-GX. That card lists 140 HP, and this one lists 240 HP. The rarity there is Rare, and here it is Rare Rainbow. Kouki Saitou illustrated that card, and 5ban Graphics illustrated this one. Retreat cost there is 1, and here it is 2. 17 other cards of Decidueye list a different HP.
Feather Arrow is listed as Ability. Once during your turn (before your attack), you may put 2 damage counters on 1 of your opponent's Pokémon. The attack Razor Leaf lists 90 damage. The cost is Grass, Colorless, Colorless. Hollow Hunt-GX is another attack lists no damage number. The cost is Grass. Put 3 cards from your discard pile into your hand. (You can't use more than 1 GX attack in a game.) Weakness is Fire ×2. Retreat cost is 2. The card text says: Pokémon-GX rule: When your Pokémon-GX is Knocked Out, your opponent takes 2 Prize cards.
I keep a set binder for Guardians Rising, meant to hold every card of that set. This card is one slot in the Guardians Rising set binder. A generation binder holds one card of each species. Decidueye can fill a slot in Generation 7 binder (Alola). Themed lists that include this exact card are Alola starters. I still need this card.
