Echo Circlet

Multi-block is a defensive primitive usually welded to a specific body: certain Wall variants and old guardsmen could hold off two attackers at once because the rules text said so. Stapling that clause onto an Equipment frees it from any one creature: cheap to deploy, cheaper to relocate, and able to turn whatever you control into a two-attacker roadblock. The math it changes is the math of going wide. An attacker normally trades one-for-one in the blocking step, so a swarm gets through on sheer count; an equipped blocker absorbs two attackers, eats one or both, and shrinks the assault by more than its single body's worth. Against token strategies and wide aggressive boards that arithmetic is the entire point, and the trivial equip cost lets you shift the Circlet onto whichever blocker the attacker is least prepared to lose. The catch is that it does nothing on offense and nothing in isolation: with no second attacker to stop, it sits inert, and against a deck that wins through one oversized threat the extra-block clause grants nothing the creature could not already do. It is narrow by construction, an answer keyed to a particular board state rather than a card that improves a creature in the abstract. The upside only materializes when the opponent has committed multiple bodies to combat, which is precisely the situation the equipped creature was already losing.
