Horse

Horse is a creature type used for cards that equine creatures; large mammals with solid hoofs and a flowing mane and tail, used for riding, racing, and to carry and pull loads.

Description
The wild horse (Equus ferus) is a species of the genus Equus, which includes as subspecies the domesticated horse as well as the undomesticated Tarpan. The genus Equus also includes Donkeys. Note though these biological terms may not make sense in a context involving magic. Further related races are Unicorns, Noggles, Pegasi and the sapient Centaurs.

Horses have been associated with all colors of mana, but are most typically found in white (as heroic steeds, or simply amoral wild animals of the plains) or in black (as literal nightmares).

History
The first creature to bear the type Horse was Zodiac Horse in Portal Three Kingdoms (though the Nightmare from Alpha was later issued errata to become a Horse as well).

Hour of Devastation introduced a Horse Lord with Crested Sunmare.
