Enchantment, 2WW (4)
Rare
Whenever a creature deals damage to you, put a gold counter on it.
Each creature with a gold counter on it is a Wall in addition to its other creature types and has defender. (Those creatures can't attack.)
When Aurification leaves the battlefield, remove all gold counters from all creatures.
Illus. Gary Ruddell

10/1/2008: Aurification gives the creature type "Wall" to creatures with gold counters on them in addition to granting them defender.
