Yes. Because, one way or another, you probably won't use more than half a dozen spells. At most, ten, and that's on Tuesdays. But it's cool to know all the spells for **FREE**! To be able to spend a turn on an expert trap or an expert unholy word! To get a second nuke in the school of chaos that you won't use because you already have the first one. This is much better than dealing or receiving twice as much damage, or than instantly doubling your army, or than messing with the karma of the enemy army.
