Devotion

When you attack, deal full damage to the
opponent and 2 more instance of +2 damage.
(If the enemy dies before instances are applied,
apply instances to Trample damage.)
Equipped creature gains +2 power and Trample.
Only one Primary Weapon can be equipped to a
creature at a time. If a creature already has one
equipped, replace the artifact and return the last
artifact to your deck.
