Description
Released in 2010 as part of the Magic 2011 core set, Quag Sickness is a black Enchantment — Aura card designated as number 111. This foil variant features artwork by Martina Pilcerova and serves as a foundational piece for collectors focusing on the M11 set code. As an Aura, it attaches to a creature to apply a persistent penalty, reducing the target's power and toughness by one for every Swamp in the controller’s library. This mechanical interaction makes it a functional tool for black-aligned strategies that rely on land count to weaken opponents' creatures. The foil finish adds a distinct visual appeal that sets it apart from the non-foil common version, making it a desirable target for finish-oriented collectors. While the original rules text defines its specific gameplay role, the card remains a recognizable component of the Magic: The Gathering trading card game history. Collectors often seek this card number to complete their M11 base set collections or to build themed decks centered around swamp-heavy mana bases. By focusing on the structural identity of the product, we help collectors identify exactly which card they need for their library. Whether you are hunting for the foil treatment or simply need card #111 to round out your 2011 core set, understanding the card's design and function is key to appreciating its place in the game's extensive catalog. This release stands as a clear example of the strategic depth introduced in the Magic 2011 expansion.
