Top 10 Most Valuable Storm Emeralda Cards (GBP)

August 18, 2026

Storm Emeralda - Pokemon Mega Evolution set - the most valuable cards ranked, led by Mega Rayquaza ex

Portal TCG · Mega Evolution

Some sets arrive quietly. Storm Emeralda did not. The Japanese Mega Evolution set (M6) dragged the hobby straight back to Hoenn — Kyogre, Groudon, Zinnia and a returning Mega Rayquaza that immediately became one of the most chased cards of the year.

We pulled the current GBP numbers and ranked the ten most valuable cards in the set, ungraded value first with the PSA 10 price alongside. It's a top-heavy list — the sky dragon takes three of the top four slots — but the tail is where the value hunters should be looking.

Here's the countdown, from a twelve-quid Hoenn legendary all the way up to a four-figure Rayquaza.

All card prices sourced from PriceCharting, captured August 2026. On a set this new, prices move fast — treat them as a snapshot, not a live quote.

The tail-ender with teeth. Mega Golisopod ex rounds out the ten — the cheapest card here to buy raw, but its special art still commands a PSA 10 near £86. Proof that in a set this deep, even the bottom of the top ten carries a real gem-mint premium.

Groudon 84, Storm Emeralda Illustration Rare

9. Groudon

Storm Emeralda · #84 · Illustration Rare

Ungraded

£12.40Ungraded

PSA 10

£91.68PriceCharting PSA 10

Hoenn's land, and the widest raw-to-graded jump on the whole list. Groudon's illustration rare costs about the same as Kyogre raw, but a PSA 10 climbs past £90 — more than seven times the ungraded price. If you pull one clean, it's worth the grading queue.

Kyogre 80, Storm Emeralda Illustration Rare

8. Kyogre

Storm Emeralda · #80 · Illustration Rare

Ungraded

£12.99Ungraded

PSA 10

£84.49PriceCharting PSA 10

Hoenn's sea. Kyogre's illustration rare leans hard on the set's Emerald nostalgia, and it's one of the prettier art cards in the run. Barely into double figures raw, but a clean PSA 10 already sits near £85 — a tidy multiple on a card most people will open and sleeve without a thought.

Mega Golurk ex 109, Storm Emeralda Special Art Rare

7. Mega Golurk ex

Storm Emeralda · #109 · Special Art Rare

Ungraded

£13.21Ungraded

PSA 10

£93.51PriceCharting PSA 10

A sleeper special art. Mega Golurk ex isn't a headline name, but its full-art is genuinely striking and it sits right in the affordable-chase sweet spot. Raw it's pocket money; a PSA 10 is seven times that. The kind of card that's easy to overlook now and annoying to buy later.

Kecleon 88, Storm Emeralda Illustration Rare

6. Kecleon

Storm Emeralda · #88 · Illustration Rare

Ungraded

£15.50Ungraded

PSA 10

£99.21PriceCharting PSA 10

The fan-favourite curveball. Kecleon's illustration rare has nothing to do with the set's power level and everything to do with charm — and charm sells. It's the most valuable of the set's cheaper illustration rares, and a PSA 10 nudges triple figures.

Zinnia's Trust 112, Storm Emeralda full-art Supporter

5. Zinnia's Trust

Storm Emeralda · #112 · Supporter · Special Art Rare

Ungraded

£26.38Ungraded

PSA 10

£153.33PriceCharting PSA 10

The set's nod to the Delta Episode. Zinnia's Trust is the full-art Supporter, and Zinnia — the Rayquaza whisperer herself — is exactly the kind of character card that ages well. Trainers like this are quiet long-term holds: modest raw, but a PSA 10 already clears £150.

Mega Rayquaza ex 95, Storm Emeralda full-art Super Rare

4. Mega Rayquaza ex — Full Art

Storm Emeralda · #95 · Super Rare (Full Art)

Ungraded

£36.89Ungraded

PSA 10

£205.62PriceCharting PSA 10

The most attainable of the set's three secret-rare Rayquazas. This full-art SR sits below the special-art and the gold, but it's a gorgeous chase in its own right — and at well under fifty pounds raw it's the sensible way to land a Storm Emeralda Mega Rayquaza. Graded, it still clears £200.

Raikou ex 108, Storm Emeralda Special Art Rare

3. Raikou ex

Storm Emeralda · #108 · Special Art Rare

Ungraded

£57.50Ungraded

PSA 10

£297.36PriceCharting PSA 10

The best of the non-Rayquaza chases. Raikou ex's special art is a genuinely gorgeous card, and it's the clear #3 — a big step down from the dragons, but a big step up from everything below it. Raw it's affordable; a PSA 10 multiplies it more than fivefold.

Mega Rayquaza ex 110, Storm Emeralda Special Art Rare full-art

2. Mega Rayquaza ex — Special Art

Storm Emeralda · #110 · Special Art Rare

Ungraded

£461.68Ungraded

PSA 10

£2,343.12PriceCharting PSA 10

The special-art Mega Rayquaza — the full-art alternate that plenty of collectors love even more than the gold. It's the card that makes the set photograph so well, and the market agrees: comfortably the second most valuable card here, with a PSA 10 well over £2,000. Two Rayquazas in the top two tells you everything about this set.

Mega Rayquaza ex 113, Storm Emeralda gold Ultra Rare, the set's most valuable card

1. Mega Rayquaza ex — Gold

Storm Emeralda · #113 · Ultra Rare (Gold)

Ungraded

£826.37Ungraded

PSA 10

£4,159.59PriceCharting PSA 10

The card the whole set is built around. Storm Emeralda's gold-bordered Mega Rayquaza ex is the ceiling piece — the one that turns a good box into a great one. Ungraded it already sits near four figures, and a PSA 10 pushes past £4,000. If Storm Emeralda has a grail, this is it.

Storm Emeralda is that rare modern set that's genuinely fun to rip and genuinely worth chasing — a Hoenn reunion with a Rayquaza sitting on top of it.

Want to hunt the Mega Rayquaza yourself? We stock Storm Emeralda sealed at Portal — Japanese booster boxes and packs — so you can chase the whole list straight from the wrapper.

Rip smart, collect better.
