Description
As card number 155 in the set, this foil variant captures the attention of collectors who appreciate the creative depth found within the Unstable series. The card is classified as an Artifact Creature in the Magic: The Gathering trading card game, featuring a mana value of 7 and a power/toughness of 3/3. What sets Modular Monstrosity apart is its dynamic rules text, which interacts directly with the flow of the game.

The foil finish enhances the visual appeal of the card, making it a desirable addition for those building collections of rare artifacts or thematic construct creatures. Collectors often seek out cards from the Unstable set due to their unique artwork and unconventional gameplay mechanics. Modular Monstrosity offers a blend of strategic depth and whimsical design that appeals to both veteran players and newcomers.
