Yeah, apprentice is simple, dude. Anybody who's confused by it probably just hasn't realized that it doesn't enforce any rules, it simply allows you to simulate the manipulation of a deck of cards. Either that or you read rasko's game logs and think that there's no GUI where you can actually see the cards. Admittedly you'll need to fiddle around for a few minutes checking out what all the menus do so you know how you might recreate certain game mechanics, but it's really easy, point-click-and-drag kind of stuff.
