Armory of Iroas (JOU 158)

Artifact — Equipment • Mana cost: {2} • Journey into Nyx • Uncommon

Whenever equipped creature attacks, put a +1/+1 counter on it.
Equip {2} ({2}: Attach to target creature you control. Equip only as a sorcery.)

From a distance the weapons look pristine, but in fact they are tarnished and dented, each as unique as the champion who carried it to battle.
