All cards with horsemanship appear in Portal Three Kingdoms. Until the set was made legal for Vintage and Legacy in October 2005, it had the distinction of being the only keyword ability existing outside of Un-sets that did not appear on a single card legal in any tournament format.
When it became legal, R&D debated the ability and what impact it might have in the same environment as flying. They considered to errata it so that horsemanship creatures could be blocked by fliers. In the end they came to the conclusion that the creatures with horsemanship just weren't aggressive enough to worry about.
