A tempo / control deck. Take control of or copy the biggest threats on the board. Use counterspells to mitigate threats and prevent yourself from losing the game. Manage the boardstate with cards like Cyclonic Rift, AEtherspouts, and Ixidron. Use the 1/1 haste insects from The Locust God strategically to chump block or to chip away at enemy life totals and Planeswalker loyalties. Remember that Polymorphist's Jest can be used to get around indestructible hexproof creatures and can be cast during combat.
Take advantage of using Counterbalance, Sensei's Divining Top, Soothsaying, Ponder and Brainstorm. Remember to save your fetch lands so you can shuffle your deck as needed.
Win the game by holding a counterspell and casting something like: Insurrection, Reins of Power, Mob Rule, or Blasphemous Act / Chain Reaction + Repercussion. If all else fails or the game starts to stall out just draw as many cards as you can and attack with 1/1 haste insects from The Locust God.
Don't forget you can cast Time Stop in response to a spell, during an opponent's upkeep, or even during the combat phase to end the turn. Use Cunning Wish to access the wish sideboard in case of emergency. If you get Thada Adel, Acquisitor out early the play is usually to attack and cast a mana rock from the opponent's deck.
Ulamog, the Infinite Gyre is included primarily to avoid getting milled to death and can be replaced with something like Niv-Mizzet, Dracogenius if your playgroup isn't running any mill effects.
