(If you are unfortunate enough to have a group of people that's not exactly a power of two, you will need to have some players skip a round. To keep things fair, give them enough more random cards to double their number. This is the same as imagining they beat someone else at their own level instead getting a bye.)
Update 2012-07-19: Dave Bonner points out that there's already a Highlander Magic variant in which "there can only be one" copy of each card. I don't think it's as good a fit for the name, but they got there first. So I should probably call this something else. Ideas?
 Magic has the problem that in standard play the amount of money you're willing to spend on it has a large effect on how well you do.  You build decks from cards you own, there's an economy around the cards based on how good they are, and to a large extent you can buy success. There are tournaments that try and deal with this in various ways, like having the contestants begin by drafting from a shared pool, and this is another approach along similar lines.
 From the perspective of a game designer this may not be a 'problem', and MMOs have learned from Magic's example in harnessing people's desire to pay money to do better, but it's not something I enjoy.
