Character and collecting appeal
Reptiles are a small Type that has grown with modern archetypes. In play, it is a card for banishing cards and Special Summoning. Its once-per-turn limits are typical of modern card design.
Version and identification
Check the code printed below the artwork on the right: it should read MAMO-EN064. MAMO-EN064 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 €0.36, a PSA 9 for €5.35 and a PSA 10 for €28.31. Our monthly prices for it go back to September 2026. It is trading at or near its highest recorded value.
Grading and population
A PSA 10 sells for 78.6× the ungraded price and 5.3× 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: an active market (17 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. Past prices do not guarantee future ones. This is not financial advice.
Before you buy
Expect to pay around €0.36 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €5.35. Ask the seller to show the code MAMO-EN064 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.
