Market outlook
Stable Outlook 8/10
Post-release hype peaked with ¥94k gold sales, but Double Rare dipped -4.8% in last 30 days due to pack openings; flagship status supports floor
Next months. Stable to slight rise with tournament play; watch graded 10 pops
Long term. Moderate appreciation as key Ninja Spinner chase card, potential 20-30% growth if meta-relevant
History
Greninja is the final evolution of Froakie, a Water/Dark-type Pokémon from Generation VI (Pokémon X and Y). Known as the 'Ninja Pokémon,' it draws inspiration from ninja aesthetics with stealth, agility, and shuriken-like Water Shuriken moves. Mega Greninja ex represents a Mega Evolution form, exclusive to the TCG's Mega Evolution era, emphasizing high-risk, high-reward gameplay with abilities like placing damage counters remotely, tying into its tactical, speed-focused theme.

Collector notes
Condition. Check for centering on Full Art borders, print defects on holo patterns, edge whitening, surface scratches on glossy secret rare finish; common flaws include minor corner dings from packs and DNA swirl print lines on Mega ex artwork
Storage. Use semi-rigid holders or top-loaders with sleeves; store in cool, dry environment away from sunlight to prevent holo oxidation; avoid stacking without dividers for Full Art variants
Authenticity. Verify Japanese text (ニンジャスピナー, M4-098/083), correct holo numbering alignment, UV-reactive security ink on edges; compare to official scans from Pokebeach or PriceCharting; fakes often have blurry artwork or incorrect rarity symbols; graded/graded grading recommended
