Description
Modular Monstrosity, designated as card number 155 in the 2017 Unstable expansion, represents a distinct entry in the Magic: The Gathering trading card game. Illustrated by Alex Konstad, this Artifact Creature — Construct requires a mana cost of {7} and enters the battlefield as a 3/3 creature. The card's design centers on a highly interactive ability that reacts to opponents' spell choices throughout the match. The core mechanic allows the controller to adapt to the game state. Whenever an opponent casts a spell, you have five seconds to select a keyword ability that has not been chosen for a card named Modular Monstrosity that day and that has appeared on a creature card. If a selection is made, this creature gains that ability. Failure to choose within the time limit results in the creature losing all keyword abilities. This structure creates a dynamic gameplay loop where the card's power shifts based on opponent interaction and timing. Collectors of the Unstable set often seek out Modular Monstrosity for its humorous tone and unique mechanical design. As part of Magic: The Gathering's silver-bordered product line, the set encourages unconventional strategies and creative card interactions. The card's ability to change its capabilities mid-game makes it a memorable piece for enthusiasts of the format. Its presence in the Unstable subset highlights the game's willingness to experiment with complex, rule-bending mechanics. Whether building casual decks or collecting specific set members, this card stands out for its reactive nature and thematic fit within the expansion's chaotic aesthetic.
