The spells available range from searching the expansion decks to manipulating the Event die. The one that stood out was the Countermagic card which allowed actions played by the opponent to be denied at the cost of 2 magic points. There are also purple buildings and magic action cards that can be played through the use of these magic points. The card I found extremely useful was Materialization which allowed a free city upgrade with a mere 2 magic points provided the player possesses at least 2 wizards in his or her principality.
While I lost a close game to Van 12-13, it was an interesting experience playing with this expansion deck and I look forward to incorporating some of these cards into my Tournament deck the next time round.
