Okay for Worlds next year i think it would be awsome if the format was both Draft and Modified. It would be pretty simple as far as organization goes. All it would require is at least 12 rounds(more than 2 days :-\) 6 rounds of draft, and 6 rounds of modified. for the 6 draft rounds it should be separated into 2 drafts. The drafts should be separted into pods of 8 and have the 8 players play each other, that way the card pool is the same. The draft would take 3 rounds. Then on day 3 just have elimination rounds using their modified decks.
