Here's the lowdown on Faction Wars at GenCon 2008:
1) Players use constructed single-faction decks
2) Cards can provide other factions' resources (Johnny Badhair), but cannot require a faction resource beyond the single primary (no Wedding Gifts)
3) Table placement during the tournament will be such that no two decks of the same faction will compete against each other (barring an absurd influx of a single faction).
4) The finals will consist of the top players of each faction.
5) The final winner's faction will play a substantial role in the set following Empire of Evil.
Event starts at noon local time on Thursday, August 14th at GenCon 41, Indianapolis, Indiana, United States, North America, Earth, Milky Way...
