Fog is a common rarity card from the Magic 2012 set in Magic: The Gathering, identified by its collector number #173. Valued at approximately $0.22, it serves as a strategic defensive option by preventing all combat damage during a turn. The artwork by Jaime Jones adds visual appeal, although its low market value reflects its utility in gameplay rather than collectibility. Collectors may appreciate its role in various green decks focused on stall tactics.
