Supply Line

When Supply Line enters the battlefield, forge a
Sword and a Shield. (Create a colorless Sword
artifact Equipment token with "Equipped creature gets
+1/+0" and "Equip {1}" and a colorless Shield
artifact Equipment token with "Equipped creature gets
+0/+1" and "Equip {1}".)
Tap an untapped creature you control: Return
Supply Line to its owner's hand. Activate this
ability only if a creature you control is enhanced.
(A creature is enhanced if it's equipped or enchanted.)
