I found some articles for all you Prerelease goers.
Brian David-Marshall (BDM) wrote an article up for the main site where he talks with Mike Turian, who provides some valuable insight since he's played with the cards already. I think the most interesting thing to note is that 18 lands is the norm, even with acceleration like Everflowing Chalice. Lands are very, very important in Zendikar, but in Zx6 Sealed, 17 lands was the norm anyway. That has apparently changed because of Multikicker. You want to be manaflooded (at least more than you usually do).
Conley Woods wrote up this for getting value out of your Prerelease.
