The new Official Tournament Store Championships (OTS Championships) provide Duelists with more opportunities to qualify for the World Championship. By winning, you earn the title of “Store Champion”, an invite to Worlds and a OTS Championship game mat featuring a monster such as “Star Eater”. Placing second in one of these events also earns you an invite.
The tournaments are held in Swiss format, with the number of rounds dependent on how many entrants there are. There are no playoffs, at the end of the Swiss rounds, the Duelist listed number 1 in the standings is crowned champion.
These events begin on September 28, 2013 at select stores.
