For the horde is a good idea, but may need to be tweeked a little. I like that it gives the Orcish player more units from barbarian ranks, but I don't like how it esentially reveals almost the entire map. Orcs never struck me as the omnicient type, and even though the units are coming from all over, thier world knowledge and maps would be suspect. Getting instant contact with ever civ in the world is a bit uncharastic as well.
