Upper Deck will release The Dark Emperor, a new structure deck, on April 2nd.  The pack will include a 40-card deck, including a new Ultra Rare card, plus a Dueling Guide, game mat, and rulebook.  The deck includes some 'highly desirable' reprints and some new cards. 

 

The Dark Emperor will allow players to banish opponents card to another dimension.  The deck is built around a powerful Dark Monster card, 'Caius the Shadow Monarch.'  It will combine well with the Dark army from the Phantom Darkness booster set.   

 

The Dark Emperor is for the intermediate player, with strong cards for the tournament-level player.
