Peat Bog

Peat Bog first appeared in the Mercadian Masques expansion, released by Wizards of the Coast in 1999. The card was designed as part of a cycle of lands that provided two mana of a single color at the cost of entering the battlefield tapped and requiring the sacrifice of a land, reflecting the set's thematic focus on resource management and the industrial, mercantile nature of the plane of Mercadia. The artwork, illustrated by Rob Alexander, utilizes a dark, somber palette to evoke the stagnant and treacherous nature of a swampy landscape, aligning with the card's function as a temporary but powerful mana source.

The card was later included in The List, a curated selection of cards from Magic: The Gathering's history that occasionally appear in Set Boosters. Its inclusion serves as a nod to the game's long-running mechanical exploration of 'depletion' lands, which prioritize immediate tempo over long-term stability. While the card is often discussed by players for its utility in specific niche archetypes, it remains a distinct example of late-nineties card design that challenged players to balance land counts and mana efficiency.
