Description
The Septic Rats foil card is a distinct creature from the Magic: The Gathering Mirrodin Besieged expansion, released in 2011. Identified as card number 55 with the set code MBS, this uncommon black mana creature brings a unique mechanical threat to the game. As a 3-mana Creature — Phyrexian Rat, it commands a mana cost of {1}{B}{B} and possesses a base power and toughness of 2/2. The card's strategic value stems from its Infect ability, which allows it to deal damage to creatures in the form of -1/-1 counters and to players in the form of poison counters. This makes it a potent tool for aggressive strategies aimed at quickening the path to victory. Furthermore, it features a dynamic triggered ability: whenever Septic Rats attacks, if the defending player is already poisoned, the creature gains +1/+1 until the end of turn. This scaling power encourages players to build around poison counters, rewarding timing and board state awareness. Collectors of Magic: The Gathering often seek out the foil treatment of this card for its shimmering finish, which elevates its visual appeal within the Mirrodin Besieged set. Designed by Cos Koniotis, the card represents a key piece of the Phyrexian narrative that permeates the Mirran plane during this era. Whether you are building a competitive deck focused on poison or expanding your collection of foil uncommons from 2011, the Septic Rats offers both mechanical depth and aesthetic charm. Its straightforward yet impactful design makes it a memorable addition to any Magic: The Gathering enthusiast's library, bridging the gap between casual play and strategic depth.
