Tainted Wisdom #MRD-E081 collector guide

About Tainted Wisdom

Tainted Wisdom is an Effect Monster, printed as MRD-E081 in Metal Raiders (2002) as a Common. It is a Level 3 DARK Fiend monster with 1,250 ATK and 800 DEF. 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 306th of the 508 Metal Raiders cards we track. The top card is Gate Guardian at €301.65.

Character and collecting appeal

Fiends are one of the largest Types in the game, home to many of its darker and more unusual designs. Skull Knight mentions Tainted Wisdom in its text, which keeps it relevant.

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-E081. The E in MRD-E081 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 Common version. Commons have a plain name and no foil. Metal Raiders has 3 other printings of Tainted Wisdom: MRD-081 (€0.89), MRD-081 1st Edition (€0.97) and MRD-E081 1st Edition. 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. Past prices do not guarantee future ones. This is not financial advice.

Before you buy

Expect to pay around €1.56 for a clean ungraded copy; played copies sell for less. Ask the seller to show the code MRD-E081, 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.
