Let me summarize.
We'll play Good versus Evil in a group stage, with the top 4 Good and 4 Evil factions advancing to the quarterfinals as JonnyP described (best against worst). The final will consist of a maximum of 3 games.
In the group stage/playoffs/final, we'll list the factions from the full list at the beginning of each stage, reducing the list of unplayed factions. In the group stage, you can't play more than 2 games with the same faction.
If, by the final, there are only Good or Evil factions, that's okay.

If there are no questions, we'll start the tournament tomorrow.
