Liquid Beast [1st Edition] #MRL-023

Liquid Beast [1st Edition] #MRL-023 collector guide

About Liquid Beast

Liquid Beast is a Normal Monster, with flavour text instead of an effect, printed as MRL-023 in Magic Ruler (2002) as a Common. It is a Level 3 WATER Aqua monster with 950 ATK and 800 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 293rd 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. Normal Monsters like this one are mostly collected for their art and to complete the set.

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 MRL-023. The code MRL-023, without a language letter, marks the original North American printing. European English copies have an E in the code, such as MRL-E023, and are priced separately. It is the Common version. Commons have a plain name and no foil. Magic Ruler has 3 other printings of Liquid Beast: MRL-023 (€0.15), MRL-E023 and MRL-E023 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 €0.20, a PSA 9 for €14.49 and a PSA 10 for €47.26. Our monthly prices for it go back to October 2021. Over the last 12 months ungraded copies are down 84%, and flat in the last month. Its highest monthly ungraded value was €1.29 in October 2025, 84% above today. PSA 10 copies have moved down 3% over the same 12 months. 1st Edition copies sell for about 1.3× the Unlimited printing (€0.20 against €0.15).

Grading and population

A PSA 10 sells for 236.3× the ungraded price and 3.3× a PSA 9. That gap is small, so grading fees may outweigh the gain unless the card is for your own collection. 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 October 2025 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; an active market (34 recent completed sales), so it is easy to sell. Against it: falling prices, down 84% in a year. Card prices can fall as well as rise, so this is not financial advice.

Before you buy

Expect to pay around €0.20 for a clean ungraded copy; played copies sell for less, and a PSA 9 costs about €14.49. Ask the seller to show the code MRL-023, 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.
