Ameba #MRL-010

Ameba #MRL-010 collector guide

About Ameba

Ameba is an Effect Monster, printed as MRL-010 in Magic Ruler (2002) as a Rare. It is a Level 1 WATER Aqua monster with 300 ATK and 350 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 183rd of the 321 Magic Ruler cards we track. The top card is Blue-Eyes Toon Dragon at €223.11.

Character and collecting appeal

Aqua monsters often work with water Field Spells such as Umi. Its effect centres on dealing damage.

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-010. The code MRL-010, without a language letter, marks the original North American printing. European English copies have an E in the code, such as MRL-E010, and are priced separately. It is the Rare version. Rares have a silver-foil name and plain artwork. Magic Ruler has 3 other printings of Ameba: MRL-010 1st Edition (€1.78), MRL-E010 (€1.40) and MRL-E010 1st Edition (€2.53). Each has its own price, so match the code, edition and rarity exactly.

Grading and population

A PSA 10 sells for 71× the ungraded price and 11.1× 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: it comes from the first years of the English game, which are no longer printed; an active market (27 recent completed sales), so it is easy to sell. Past prices do not guarantee future ones. This is not financial advice.

Before you buy

Expect to pay around €1.26 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €8.02. Ask the seller to show the code MRL-010, 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.
