Bellowing Tanglewurm

The Bellowing Tanglewurm was released in 2010 as part of the Scars of Mirrodin set, a landmark return to the metallic, artifact-focused plane of Mirrodin. In the narrative arc of the game, the set depicted the Phyrexian invasion of the world, where the Tanglewurm represents the corrupted biological horrors emerging from the Tangle, the world's forested region. It was designed as a thematic centerpiece for green-aligned decks, emphasizing the set's focus on poison counters and creature-based combat efficiency.

The card was illustrated by artist Matt Cavotta, who sought to capture the visceral, unsettling aesthetic of the Phyrexians by blending organic forest textures with jagged, biomechanical features. Its design focused on providing a powerful offensive edge, granting other green creatures the ability to bypass smaller blockers. Upon release, it was well-received by players for its impact in limited formats, where its menace-granting ability served as a reliable finisher for aggressive strategies.
