Guardian of the Labyrinth [1st Edition] #MRD-E083 collector guide

About Guardian of the Labyrinth

Guardian of the Labyrinth is a Normal Monster, with flavour text instead of an effect, printed as MRD-E083 in Metal Raiders (2002) as a Common. It is a Level 4 EARTH Warrior monster with 1,000 ATK and 1,200 DEF. Metal Raiders was the second English booster set. It added Summoned Skull, Gate Guardian, Mirror Force and Change of Heart, and many of its cards shaped how the early game was played. Ungraded, this printing ranks 212th of the 508 Metal Raiders cards we track. The top card is Gate Guardian at €301.65.

Character and collecting appeal

Warriors are one of the oldest and largest Types, and have had support in almost every era of the game. Normal Monsters like this one are mostly collected for their art and to complete the set. Arsenal Summoner and Giltia the D. Knight mention Guardian of the Labyrinth in their text, which keeps it relevant.

Version and identification

This guide covers the 1st Edition printing. The words "1st Edition" are printed below the artwork on the left; copies without them are the Unlimited printing and usually sell for less. Check the code printed below the artwork on the right: it should read MRD-E083. The E in MRD-E083 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 Common version. Commons have a plain name and no foil. Metal Raiders has 3 other printings of Guardian of the Labyrinth: MRD-083 (€1.04), MRD-083 1st Edition (€1.16) and MRD-E083 (€1.50). Each has its own price, so match the code, edition and rarity exactly.

Grading and population

A PSA 10 sells for 61.5× the ungraded price and 12.5× a PSA 9. That gap is big enough that grading a sharp, well-centred copy can pay for itself. Early English Yu-Gi-Oh! cards often have off-centre cuts and wear on the dark brown back borders, which is why high grades are hard to reach.

Investment potential

In its favour: a price well below its May 2026 peak, which some collectors see as room to recover; it comes from the 1st Edition run of an early English set, which will never be printed again. Against it: thin trading, so selling quickly can mean accepting a lower price. Card prices can fall as well as rise, so this is not financial advice.

Before you buy

Expect to pay around €2.35 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €11.52. Ask the seller to show the code MRD-E083, the "1st Edition" text and the Common finish clearly in the photos, as listing titles often mix up printings. Cards from 2002 often show white wear on the back edges and corners, so ask for photos of the back before you buy.
