Ash-Greninja GX from Burning Shadows is the card most Greninja fans want. Here's the honest read.
Why it's the one
It captures Ash-Greninja — the anime's most hyped form — and Greninja's popularity spans the TCG, the show, and Smash Bros. That cross-media appeal gives it unusually broad, durable demand.
Which version?
There's the standard GX, the full art, and the rainbow secret rare — the rainbow and full art carry the biggest premiums and are the collector targets. There's also an SM-series promo version worth knowing about.
Raw vs PSA 10
Raw is the affordable, great-looking buy. A PSA 10 of the rainbow or full art is the real store of value. Standard copies are common, so grade only the rare versions — run the math with the grading calculator.
Verdict
Worth it — it's the definitive Greninja and a cross-media fan icon. Buy the full art or rainbow if you want value; the standard GX is a cheap, fun pickup. See the best Greninja cards.
