《PTCG 寶可夢卡牌 25 週年收藏 擴充包》（Pokémon TCG: Celebrations／日版名稱為《ポケモンカードゲーム ソード＆シールド 25th ANNIVERSARY COLLECTION》）是寶可夢卡牌遊戲為紀念誕生 25 週年所推出的重要紀念企劃之一，在 2021 年 10 月正式登場。這個系列不僅承載滿滿的情懷，也被視為劍與盾時期最具代表性的特殊補充包之一，至今仍在收藏市場中具有極高話題性。

在日本市場，官方同步推出「25th ANNIVERSARY COLLECTION 擴充包」以及「25th ANNIVERSARY COLLECTION スペシャルセット（特別組合）」。其中，特別組合為全國便利商店限定販售商品，販售通路僅限日本各大連鎖超商，這樣的限定性也讓該商品在發售初期便迅速被搶購一空。

這款便利商店限定的特別組合，內容設計相當具有紀念與收藏價值。每一組內含四包「25th ANNIVERSARY COLLECTION」擴充包，再贈送上一包「Promo Card Pack 25th ANNIVERSARY Edition」促銷卡包，以及一枚寶可夢紀念硬幣。官方建議售價為含稅 1,188 日圓，在當時屬於相對親民、卻內容豐富的紀念商品。擴充盒則有16包。

在卡片構成方面，「25th ANNIVERSARY COLLECTION」擴充包每包內含五張卡牌，其中必定包含閃卡，並固定配置一張基本能量卡。這些卡片全部印有象徵 25 週年的藍金色「25th」標誌，視覺辨識度極高。與海外版 Celebrations 不同的是，日版擴充包存在反向閃卡（Reverse Holo）配置，使得整體收藏變化性更高。

而「Promo Card Pack 25th ANNIVERSARY Edition」則是日版獨有的重要收藏要素。這個促銷卡包每包僅含一張卡片，但收錄內容極具話題性，包含重新詮釋過去經典機制的卡牌，例如 Dark Pokémon、Light Pokémon、δ 種、Pokémon ☆、LV.X、SP 與 Prime 等過去已停用的系統。這些卡片以現代美術與排版重新設計，並搭配灑落彩紙風格的特殊閃膜，強烈喚起老玩家的記憶。不過需要注意的是，這類促銷卡與部分復刻卡片皆標註「不可於官方比賽使用」，定位明確偏向收藏用途。

值得一提的是，本次 25 週年企劃中，還包含一個極具象徵意義的「Classic Collection（經典收藏子集）」，收錄25 張高度還原過去人氣卡牌的復刻作品。這些卡片保留原始卡號、稀有度與版權資訊（早期 WotC 時代卡片則略有調整），並透過現代印刷技術賦予更高質感。日版則將這一概念獨立為促銷卡包形式發放，進一步提升稀有性。

從主題設計上來看，25 週年系列橫跨寶可夢整個世代歷史，從初代的夢幻、鳳王，到後期世代的露奈雅拉、蒼響等傳說與幻之寶可夢一應俱全。皮卡丘更是貫穿全系列，不僅有飛行皮卡丘與衝浪皮卡丘，甚至推出Pokémon V 與 VMAX 版本，象徵系列從過去走向現代的演進。

總體而言，《25th ANNIVERSARY COLLECTION》不只是一個單純的補充包系列，而是一場獻給所有寶可夢卡牌玩家與收藏家的盛大回顧。它成功結合懷舊、創新與紀念意義，無論是對老玩家、純收藏族，或是剛入坑的新玩家而言，都具有難以取代的價值。即使在發售多年後，這個系列依然被視為寶可夢卡牌史上最具代表性的紀念作品之一。

The Pokémon Trading Card Game 25th Anniversary Collection (internationally known as Pokémon TCG: Celebrations, and in Japan as Pokémon Card Game Sword & Shield: 25th ANNIVERSARY COLLECTION) is one of the most significant commemorative releases created to celebrate the 25th anniversary of the Pokémon Trading Card Game. Officially released in October 2021, this set quickly became one of the most iconic special expansions of the Sword & Shield era and remains highly valued in the collector market to this day.

In Japan, the launch of the 25th ANNIVERSARY COLLECTION expansion coincided with the release of a special product known as the 25th ANNIVERSARY COLLECTION Special Set, which was sold exclusively through convenience stores nationwide. This retail restriction significantly increased its desirability, and the product sold out rapidly upon release.

The convenience-store-exclusive Special Set was designed with both commemorative and collectible appeal in mind. Each set included four packs of the 25th ANNIVERSARY COLLECTION expansion, one Promo Card Pack: 25th ANNIVERSARY Edition, and one Pokémon-themed commemorative coin. The official suggested retail price was 1,188 yen including tax, making it relatively affordable while offering substantial value for collectors.

Regarding card composition, each 25th ANNIVERSARY COLLECTION booster pack contains five cards, one of which is guaranteed to be a holographic card, along with a basic Energy card. All cards in the Japanese release feature a distinctive blue-and-gold “25th” anniversary logo, giving the set a strong visual identity. Unlike the international Celebrations set, the Japanese version includes Reverse Holo cards, adding greater variety and collectability.

The Promo Card Pack: 25th ANNIVERSARY Edition is a particularly important element exclusive to the Japanese release. Each pack contains only one card, but the contents are highly notable, featuring modern reinterpretations of classic, discontinued TCG mechanics such as Dark Pokémon, Light Pokémon, δ Delta Species, Pokémon ☆, Pokémon LV.X, Pokémon SP, and Pokémon Prime. These cards combine contemporary artwork and layout with a confetti-style holofoil pattern, strongly evoking nostalgia among longtime players. However, most of these promotional cards are marked as ineligible for official tournament play, clearly positioning them as collector-focused items.

Additionally, the 25th anniversary project includes the highly symbolic Classic Collection, a subset of 25 cards that faithfully recreate some of the most beloved cards from earlier eras of the Pokémon TCG. These cards retain their original numbering, rarity, and copyright details, though some early-era cards omit the Wizards of the Coast copyright. Enhanced with modern printing techniques, they achieve a level of finish far beyond their original versions. In Japan, this concept was implemented through the promotional card pack format, further increasing rarity and collector appeal.

Thematically, the 25th Anniversary Collection spans the entire history of the Pokémon franchise, featuring Legendary and Mythical Pokémon from across all generations, from early icons such as Mew and Ho-Oh to later figures like Lunala and Zacian. Pikachu serves as a unifying symbol throughout the set, appearing in multiple nostalgic forms including Flying Pikachu and Surfing Pikachu, each released as both Pokémon V and Pokémon VMAX, symbolizing the evolution of the game from its origins to the modern era.

Overall, the 25th ANNIVERSARY COLLECTION is far more than a standard expansion. It represents a carefully crafted celebration of Pokémon TCG history, successfully blending nostalgia, innovation, and commemorative significance. Whether for veteran players, dedicated collectors, or newcomers to the hobby, the set holds enduring value and is widely regarded as one of the most important and memorable releases in the history of the Pokémon Trading Card Game.
