Edit - Updated for BoT
This is the deck I used to get to masters this month. It's a control deck making use of Alessi, Pearl Abbey Smuggler and lots of spells. Later in the game, Display of Vision and Petition can grab Cylixes, letting your power development draw a card, so that you have fewer dead draws. Alessi, Diana, and a couple relic weapons also give you armor for Plea for Aid, and if you don't have any, just grabbing Alessi is ok as well.
