Cathar's Shield⁣ - Eldritch Moon⁣ (Common)⁣ [192]

Cathar's Shield is an equipment that grants a creature +0/+3 and vigilance, allowing it to defend while still being able to attack. Its zero mana cost makes it easy to play, and the +3 toughness can help bolster your creatures against aggressive strategies. However, the equip cost of {3} means you'll want to use it on creatures that are already established on the battlefield rather than those that are just entering play.
