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 Collector's Rare version. Collector's Rares have a textured holographic finish over the artwork and frame.

Grading and population
A PSA 10 sells for 18.5× the ungraded price and 3.7× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. Modern foils can leave the pack with scratches, print lines or a slight curl, so even fresh copies do not always reach a 10.
Investment potential
In its favour: an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 14% in a year; large modern print runs, which tend to cap prices unless a card becomes iconic. Past prices do not guarantee future ones. This is not financial advice.
Before you buy
Expect to pay around €2.11 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €10.50. Ask the seller to show the code RA03-EN023 and the Collector's 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.
