Black Carriage
From MTG Salvation Wiki
The Black Carriage was a carriage pulled by four black horses and owned by Baron Sengir of Ulgrotha, that was sometimes seen riding down Carriage Road. It nearly killed Cassie An-Havva, but she was saved by a Brass Man. Sengir chose villagers to be coachmen, and, at the end of the night, fed them to the twisted horses.
