Wall of Caltrops
Banding-on-a-trigger is the design curio worth pausing on. Most Legends-era banding lived on the card as a static keyword, which meant the damage-division trick was always available but always obvious: opponents simply refused to attack into the bander. Here, the keyword arrives only when two Walls gang-block the same creature with no help from anything else, which is a remarkably specific puzzle to solve for two mana and a 2/1 body that cannot attack. The reward, when you do solve it, is the defender's grail: the ability to soak a large attacker with a chump and assign the lethal damage to the bigger Wall, keeping your blocker alive. The card is a thesis statement for a Wall-tribal deck that Legends gestured at but never quite delivered, and the trigger structure (conditional on a fellow Wall, spoiled by a non-Wall blocker) reads as an early attempt to gate a powerful combat-math ability behind a tribal commitment rather than a mana cost. The mechanic has aged into near-illegibility: banding's damage-division rules are some of the most-errata'd text in the game, and a Wall that conditionally gains banding is a sentence that asks the modern reader to consult two separate rulebooks. As a design artifact, though, it captures Legends in miniature: a strange idea, gated by a stranger condition, printed at common.
