An entire mechanical category exists to be defensive, and this enchantment exists to break that contract. Walls are designed as one-way bargains: high toughness, low (often zero) power, the defender keyword locking them behind the combat math as pure blockers. This flips the sign on the whole tribe at once, turning a board of high-toughness roadblocks into an attacking force whose stats were never meant to push damage. The trick has always been finding Walls whose power was incidentally high, or whose toughness could be repurposed: the design rewards reading the wall corpus for outliers rather than treating it as a uniform defensive class. What makes the card more than a gimmick is that it does not buff anything; it removes a restriction, which is a cleaner and cheaper lever than the usual route of overstatting an army. The defensive shell stays intact on opponents' turns, so the cost of going on offense is only the keyword, not the body. It is a build-around in the truest sense: useless without a critical mass of Walls, but the engine that makes a pile of blockers suddenly lethal. That conditionality follows directly from the effect's narrowness, and it is exactly why a two-mana enchantment is allowed to rewrite an entire creature type's combat role.
