CROSS-CULTURAL PARALLELS

Where This Object Echoes

Japanese FolkloreEdo Period to Present

Zarude's design as a forest-dwelling protector mirrors the Kodama or tree spirits that guard sacred groves.

Ritual & Ceremonial Use

•The 'pack opening' ceremony has become a digital ritual in modern collecting culture, centered on the reveal of rare 'Amazing Rare' variants.

Meaning Through Time

2020-Present

The introduction of the 'Amazing Rare' rarity tier shifted collector focus toward card texture and multi-energy mechanics.

SET RELEASE & PRINT RUN

Released in Japan on July 10, 2020, Legendary Heartbeat introduced 'Amazing Rare' cards to the TCG. These cards featured a unique rainbow holofoil pattern that extended past the artwork frame and required three different energy types for their attacks. The set was designed to coincide with the Japanese theatrical release of 'Pokémon the Movie: Secrets of the Jungle', which featured the mythical Pokémon Zarude depicted on the pack art.

Identification is near-certain due to clear visibility of set codes, barcodes, and high-resolution images of factory-standard crimping.

2Correct Japanese '7 cards per pack' (7枚入り) notation for this specific subset
3Authentic heat-sealed crimp patterns on top and bottom edges

WHAT WOULD IMPROVE CERTAINTY

→Compare the barcode and text layout against known authentic S3a sealed boxes
