Q: How does Wizards balance a set? —Jamelle
A: Mike McArtor, copyeditor for DailyMTG:
A fun but huge question that we can't, unfortunately, answer in the space available here! But fear not, for the mighty Sam Stoddard has begun to answer this very question in his stint on the weekly column Latest Developments!
But really, if you're interested in the hows and whys of card and set balancing, there's no better place to go than Latest Developments every week. If, however, you want to learn more about how specific sets are developed, Erik Lauer and Dave Humpherys have written several features along those lines.
