Horn of the Unicorn #MRL-E054 collector guide

About Horn of the Unicorn

Horn of the Unicorn is an Equip Spell Card, printed as MRL-E054 in Magic Ruler (2002) as a Rare. 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 109th of the 321 Magic Ruler cards we track. The top card is Blue-Eyes Toon Dragon at €223.11.

Character and collecting appeal

In play, it is a card for changing ATK and DEF.

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-E054. The E in MRL-E054 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 Rare version. Rares have a silver-foil name and plain artwork. Magic Ruler has 3 other printings of Horn of the Unicorn: MRL-054 (€1.41), MRL-054 1st Edition (€1.34) and MRL-E054 1st Edition (€3.13). 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. Treat this as background, not a prediction or financial advice.

Before you buy

Expect to pay around €2.84 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code MRL-E054, the missing "1st Edition" text and the 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.
