Guardian of the Throne Room #MRL-013 collector guide

About Guardian of the Throne Room

Guardian of the Throne Room is a Normal Monster, with flavour text instead of an effect, printed as MRL-013 in Magic Ruler (2002) as a Common. It is a Level 4 LIGHT Machine monster with 1,650 ATK and 1,600 DEF. Magic Ruler was the third English booster set and brought Pegasus's Toon cards into the game. Magic Cards were later renamed Spell Cards and the set was reprinted as Spell Ruler, so Magic Ruler copies are the original printing. Ungraded, this printing ranks 266th of the 321 Magic Ruler cards we track. The top card is Blue-Eyes Toon Dragon at €223.11.

Character and collecting appeal

Machines range from early robots to modern archetypes, and the Type has a loyal following. As a Normal Monster it is collected for its artwork and its spot in the set rather than for play.

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 MRL-013. The code MRL-013, without a language letter, marks the original North American printing. European English copies have an E in the code, such as MRL-E013, and are priced separately. It is the Common version. Commons have a plain name and no foil. Magic Ruler has 3 other printings of Guardian of the Throne Room: MRL-013 1st Edition (€0.16), MRL-E013 and MRL-E013 1st Edition. Each has its own price, so match the code, edition and rarity exactly.

Price history

Today an ungraded copy of this printing sells for about €0.28, a PSA 9 for €5.35 and a PSA 10 for €36.08. Our monthly prices for it go back to October 2021. Over the last 12 months ungraded copies are down 69%, and up 47% in the last month. Its highest monthly ungraded value was €1.77 in March 2023, 84% above today. PSA 10 copies have moved down 43% over the same 12 months. Unusually, Unlimited copies currently sell for as much as or more than 1st Edition ones (€0.28 against €0.16).

Grading and population

A PSA 10 sells for 128.9× the ungraded price and 6.7× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. On cards from the early 2000s, the dark brown backs show every scuff and white edge, so top grades are scarce.

Investment potential

In its favour: a price well below its March 2023 peak, which some collectors see as room to recover; it comes from the first years of the English game, which are no longer printed; an active market (25 recent completed sales), so it is easy to sell. Against it: falling prices, down 69% in a year. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €0.28 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 MRL-013, the missing "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.
