What is the most expensive mtg legendary creature ever?

As of October 2023, the most expensive Magic: The Gathering legendary creature card is the "Black Lotus," known for its iconic status and powerful gameplay effects. However, it is not a creature card but rather an artifact. Among legendary creature cards, "The One Ring," a unique one-of-a-kind card created for The Lord of the Rings set, has fetched extraordinarily high prices at auction, reaching over $2 million. Prices for MTG cards can fluctuate significantly based on market trends and collector demand.
