Cover of Shadows

Equip {0} (Equip only as a sorcery.)
Equipped creature has Shadow and Fading 3. (This creature gets 3 fade counters on it. At the beginning of your upkeep, remove a fade counter from it. If you can't, sacrifice it.) Re-equipping Cover of Shadows does not add fade counters.
He said; and, while he said, his steps he turn'd
To secret shadows, and in silence mourn'd. -Virgil, The Aeneid
