Ungraded, this printing ranks 157th of the 331 Labyrinth of Nightmare cards we track. The top card is Torrential Tribute at €92.89.

Character and collecting appeal

Aqua monsters often work with water Field Spells such as Umi. Normal Monsters like this one are mostly collected for their art and to complete the set. Humanoid Worm Drake mentions Humanoid Slime in its text, which keeps it relevant.

Version and identification

This guide covers the Unlimited printing, without the "1st Edition" text below the artwork. 1st Edition copies of the same card have their own, usually higher, prices. Check the code printed below the artwork on the right: it should read LON-E003. The E in LON-E003 marks the European English printing. The North American printing uses a code without the letter, sometimes with a different card number, and has its own prices. It is the Short Print version. Short Prints look like Commons but were printed in smaller numbers. Labyrinth of Nightmare has 4 other printings of Humanoid Slime: LON-003 (€0.94), LON-003 1st Edition (€4.02), LON-E003 1st Edition and LON-EN003. Each has its own price, so match the code, edition and rarity exactly.

Investment potential

In its favour: it comes from the first years of the English game, which are no longer printed. Against it: thin trading, so selling quickly can mean accepting a lower price. Past prices do not guarantee future ones. This is not financial advice.

Before you buy

Expect to pay around €1.98 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code LON-E003, the missing "1st Edition" text and the Short Print finish clearly in the photos, as listing titles often mix up printings. Cards from 2003 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
