This deck has one primary goal: play Shared Fate, then Leveler.  In that order.  Get both in your hand, then play them.  Use the counters and the kill spells to keep yourself alive, but you should be constantly using the tutors and scry spells to get the cards as early as possible.  If your opening hand has nothing worthwhile, drop a whirlpool rider early for a second chance.  Use Yawgmoth's Agenda in absolute emergencies, and I recommend you save a scry spell or two for your fourth-or-fifth turn so you can ensure your opponent won't draw anything tricky from the top of your deck in the turn between playing Shared Fate and Leveler (like their own Leveler, for instance!).
