By the same logic you're using, one could argue that Ysera, Animal Companion, The Lich King, etc. are all too confusing for new players, because there's no way to tell what they do in-game without playing them. You're kinda too late to make that kind of argument by a few years. Besides, as evidenced by things like Dr. Balanced and Gelbin Mekkatorque, Blizzard aren't above wording card effects to provide some form of flavor text on the card itself.
As for the whole keyword issue, I think that discussion is best had somewhere else.
