Character and collecting appeal
Wyrms are a modern Type with eastern dragon designs. Its text is about clearing the field, banishing cards and Special Summoning. Its once-per-turn limits are typical of modern card design. It cannot be Normal Summoned, so it has to be brought out by its own conditions.
Version and identification
Check the code printed below the artwork on the right: it should read RA03-EN023. RA03-EN023 is the English printing. Other languages use their own letters in place of EN, such as DE or FR, and are priced separately. It is the Secret Rare version. Secret Rares have a rainbow-foil name and diagonal holographic artwork.

Grading and population
A PSA 10 sells for 19.3× the ungraded price and 3.9× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. Even pack-fresh modern cards can have surface scratches or curling foil, so a 10 is never guaranteed.
Investment potential
In its favour: steady demand, with ungraded prices up 10% in a year; an active market (26 recent completed sales), so it is easy to sell. Against it: large modern print runs, which tend to cap prices unless a card becomes iconic. Card prices can fall as well as rise, so this is not financial advice.
Before you buy
Expect to pay around €1.99 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €9.81. Ask the seller to show the code RA03-EN023 and the Secret Rare finish clearly in the photos, as listing titles often mix up printings. Modern foils can be scratched or curled straight from the pack, so check the surface under a light if you plan to grade.
