The Impervious Greatwurm stands as one of the most imposing creatures in the Guilds of Ravnica set, released by Wizards of the Coast in 2018. As card number 273, this foil mythic rare captures the essence of massive mana investment with a staggering 16/16 power and toughness. Designed by artist Simon Dominic, the card serves as a centerpiece for decks seeking overwhelming board presence and resilience. Its gold mana cost of seven generic mana and three green mana reflects its status as a high-impact finisher rather than an early-game threat. The card’s utility is defined by two key abilities that shape its gameplay role. The convoke mechanic allows players to tap their own creatures to help cast the spell, effectively reducing the mana cost by converting existing board assets into payment. This synergy makes it particularly effective in decks that have already established a strong presence of smaller creatures. Additionally, the indestructible trait ensures that the Greatwurm cannot be destroyed by damage or effects that say "destroy," making it a durable anchor for late-game strategies. Collectors of Magic: The Gathering trading cards often seek out foil mythic rares for their visual appeal and rarity within the set. Its design and mechanics make it a notable addition to any collection, appealing to both competitive players who appreciate its strategic potential and casual collectors who value its status as a high-rarity foil. The combination of its massive stats, unique casting mechanic, and foil treatment makes the Impervious Greatwurm a standout piece in the Magic: The Gathering catalog.
