Gate Guardian #MRD-000 collector guide

About Gate Guardian

Gate Guardian is an Effect Monster, printed as MRD-000 in Metal Raiders (2002) as a Secret Rare. It is a Level 11 DARK Warrior monster with 3,750 ATK and 3,400 DEF. No monster in Metal Raiders has more ATK. 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 28th of the 508 Metal Raiders cards we track. The top card is Gate Guardian at €301.65.

Character and collecting appeal

Gate Guardian is the giant monster of the Paradox Brothers in the anime. Summoning it means Tributing Sanga of the Thunder, Kazejin and Suijin, so it is far more popular with collectors than with players. Its effect centres on Special Summoning. It cannot be Normal Summoned, so it has to be brought out by its own conditions. Its text names Kazejin, Sanga of the Thunder and Suijin, so collectors often look for them together.

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 MRD-000. The code MRD-000, without a language letter, marks the original North American printing. European English copies have an E in the code, such as MRD-E000, and are priced separately. It is the Secret Rare version. Secret Rares have a rainbow-foil name and diagonal holographic artwork. Metal Raiders has 4 other printings of Gate Guardian: MRD-000 1st Edition (€128.18), MRD-000 Reverse Foil Error (€301.65), MRD-E000 (€17.84) and MRD-E000 1st Edition (€93.28). Each has its own price, so match the code, edition and rarity exactly.

Grading and population

A PSA 10 sells for 10× the ungraded price and 2.1× 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: steady demand, with ungraded prices up 53% in a year; a price well below its September 2021 peak, which some collectors see as room to recover; it comes from the first years of the English game, which are no longer printed; lasting fame from the anime or the competitive game; an active market (154 recent completed sales), so it is easy to sell. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €27.17 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €126.95. Ask the seller to show the code MRD-000, the missing "1st Edition" text and the Secret Rare 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.
