If you think you're an experienced enough gamer that you can skip a few steps, then you have a lot more options. Think of how everyone always complains about the beginner scenarios in scenario-based games like Earth Reborn and Last Night on Earth.
Problem is, simpler can definitely mean 'more boring', so it's good to think of this as only an intro. These cards will be simpler than most, and I think those precons include a summary of the rules as well. If you've never played Magic before, probably the best thing to do to start is to buy a complete set of the preconstructed decks, aka Intro Decks, for the latest Core Set ($30-$40).
Since I usually clutter up any thread here about any CCG with all my thoughts about how to play Magic on the cheap, and since I get PMs for advice every so often, I thought it'd be a good idea to do a write up on all the ways to play Magic for cheap so that I never have to do it again.
