Character and collecting appeal

Reptiles are a small Type that has grown with modern archetypes. Its effect centres on negating cards and effects, destroying cards and stopping attacks.

Version and identification

Check the code printed below the artwork on the right: it should read MAMO-EN091. MAMO-EN091 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 Ultra Rare version. Ultra Rares have a gold-foil name and holographic artwork.

Price history

Today an ungraded copy of this printing sells for about €1.24, a PSA 9 for €8.02 and a PSA 10 for €35.54. Our monthly prices for it go back to August 2026. Its highest monthly ungraded value was €6.65 in August 2026, 81% above today.

Grading and population

A PSA 10 sells for 28.7× the ungraded price and 4.4× 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: a price well below its August 2026 peak, which some collectors see as room to recover; an active market (25 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 €1.24 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €8.02. Ask the seller to show the code MAMO-EN091 and the Ultra 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.
