Lammasu

The lammasu is a bizarre creature type that apparently ruled Ravnica before urban sprawl took over. They now have become very rare. Lammasu have the bodies of cows, a bird's wings and a human face with horns. The only lammasu to ever be featured on a card is Hunted Lammasu, whose text alludes to rival species who have had more or less success adapting to the change of environment.
