I didn't think of it earlier: Trump magic from the Amber series by Zelazny.
The "Valdemar Series" and "Heralds of Valdemar" are actually the same, so that should bring the list down a bit ;) In that story, Valdemar is the name of the Kingdom, and the Heralds parts of that Kingdom. In any case, when I voted I selected both of those along with Final Fantasy VII. There are lots of good picks on that list, but those two are my favorite :)
