Description
The Septic Rats card from Magic: The Gathering's 2011 Mirrodin Besieged set (MBS #55) is an uncommon foil creature that appeals to players and collectors alike. As a black Phyrexian Rat with a mana value of three, this card brings a distinct mechanical identity to the tabletop experience. Its printed rules text grants it the Infect ability, allowing it to deal damage to creatures via -1/-1 counters and to players through poison counters. Beyond its inherent threat, the Septic Rats card offers strategic depth. Whenever this creature attacks, if the defending player is already poisoned, it receives a temporary +1/+1 boost until the end of the turn. This interaction makes it a compelling choice for decks built around poison strategies or those looking to leverage existing board states. The foil treatment adds a layer of visual appeal, making it a desirable addition to any Mirrodin Besieged collection. Collector interest in this card often stems from its role within the Phyrexian theme of the Mirrodin block. Whether you are building a competitive deck or completing a set, the Septic Rats foil card represents a key component of the Mirrodin Besieged expansion.
