Jon's been doing everyone a favor and writing about all matters of constructed-related things and I can say for everyone here that it's been exceedingly educational. But Jon hasn't touched on a format that I can safely consider my area of expertise.
I am, of course, talking about limited. You know: draft and/or sealed. Specifically I'm going to touch on the more common of the two in this article: draft. Most of us rarely if ever play sealed. Truthfully, the two formats may be under the same banner, but they're vastly different.
Probably the most important thing to know about limited is the environment itself. In a booster draft, it's vital to know what to expect in terms of cards, in terms of how they interact with each other, and also in terms of what to expect other people to be doing.
I'll go through each of these points with examples.
