Siege Mastodon is a common rarity creature card from the Magic 2014 set, numbered 34, with artwork by Matt Cavotta. Valued at $0.07, it features a 3/5 body for three mana, offering decent early-game presence in various formats. As a staple in some casual decks, its low market value reflects its accessibility to new players and collectors alike. Collectors appreciate its thematic relevance and art, though it remains a budget-friendly option.
