This is a deck I've been slowly building through misc trades. It's core is tempo control. It uses Sygg to keep card draw up. You will steal alot of your opponent's spells and creatures. It's fun. Probably needs more counterspells to be competitive.
Glen Elendra Liege is a great idea to turn our 2-power guys (Nighthawk etc) into Sygg triggers! Do you know if Sygg gets +2/+2 from it because it is both blue and black? Also consider Nightveil Specter for evasive disruption. You could steal a bunch of lands or a top (if you're lucky) with it!
