Osriv, Rider of the Last Horse

First Strike, Vigilance, Horsemanship
This creature cannot attack alone. If
you control a horse Osriv can attack alone.
Osriv escaped the elken on Tinael, searching
for a home to set us free of the elk. He will bring
an army of humans with steel and horses to
save us all! Killa, Bard of Ghratta Grove
