## Description

Shackles, card number 37 from the Invasion set, is a staple white enchantment in Magic: The Gathering released in 2000. As an Aura with the enchant creature subtype, this card attaches to a target creature to impose a significant tactical restriction. The primary effect prevents the enchanted creature from untapping during its controller's untap step, effectively neutralizing a key threat for a full turn cycle. This mechanism is particularly valuable in limited formats where resource management and tempo are critical to securing victory. Art by Greg Staples, the card features flavor text that hints at the narrative tension of the Invasion block, adding depth to the collectible experience for fans of the storyline. The mana cost of two generic and one white mana makes it accessible in early-game strategies, allowing players to establish board control without sacrificing long-term card advantage. The inclusion of a {W} activation ability to return the Aura to its owner's hand provides flexibility, enabling strategic repositioning or recursion in subsequent turns. For collectors focusing on the Invasion expansion, Shackles represents a fundamental piece of the set's mechanical identity. Whether you are building a deck around creature control or completing a comprehensive set collection, this card remains a notable component of the Invasion block's legacy.
