Siege Modification is a distinct Uncommon card from Magic: The Gathering's 2017 Aether Revolt set, identified by card number 99 in the AER print run. This Enchantment—Aura card focuses on enhancing Vehicle permanents, making it a functional piece for collectors building specific deck archetypes or completing the full Aether Revolt set. The card requires three red mana to cast and targets either a creature or a Vehicle, bridging the gap between traditional combat roles and the unique Vehicle mechanic introduced in this era. When attached to a Vehicle, Siege Modification causes that permanent to be treated as a creature in addition to its other types, allowing it to participate in combat where it otherwise could not. The enchantment also provides a significant power boost, granting the enchanted Vehicle +3/+0 and bestowing the first strike ability. This combination of conversion and combat enhancement makes it a strategic tool for players who rely on artifact-based aggression. The flavor text, "Perfect for getting through to the consuls," hints at the industrial and militaristic themes prevalent in the Aether Revolt storyline. Collectors often seek out Siege Modification for its utility in Vintage and Modern formats, where Vehicle decks have historically found success. Whether you are a player looking to strengthen your artifact strategy or a set builder aiming for completeness, this card represents a key component of the Aether Revolt ecosystem. Its straightforward yet powerful effect ensures it remains a recognizable and valued addition to any Magic: The Gathering collection. The card's red mana cost and Aura subtype make it easily identifiable within the game's vast card library, serving as a reminder of the innovative mechanical shifts that defined the 2017 release.
