Artefatto — Equipaggiamento
La creatura equipaggiata può bloccare una creatura addizionale.
Equipaggiare

Echo Circlet’s effect is cumulative. If it equips a creature that can already block an additional creature, now it can block three creatures. The same is true if two Echo Circlets equip the same creature, for example.
Destroying or unequipping the Echo Circlet after blockers have been declared will not undo any blocks made by the equipped creature.
