Phyrexian Swarmlord

Phyrexian Swarmlord was introduced in the 2011 Magic: The Gathering expansion New Phyrexia, representing the culmination of the Phyrexians' conquest of the plane of Mirrodin. Designed by Wizards of the Coast as part of the set's focus on the 'infect' mechanic and the proliferation of oily corruption, the card embodies the faction's parasitic and overwhelming nature. It was created to function as a top-end threat in green decks, rewarding players for successfully spreading toxic counters across the battlefield.

The creature's illustration was crafted by artist Igor Kieryluk, who focused on the grotesque, biomechanical aesthetic central to New Phyrexia's visual identity. The design captures the swarm-like essence of the entity by producing insect tokens, reinforcing the theme of inevitable expansion. Upon release, the card was received as a flavorful, albeit high-mana, centerpiece for casual play and Commander formats, where its ability to scale with the game state remains a distinct mechanical hallmark of the set.
