This is very hard to say. Maybe his legendaries would make the difference for him.

I think you have a chance if you play as much Aggro as possible to put your opponent under pressure. Under pressure he maybe will make mistakes.
As Deception you are able to hide one of your own creatures to protect them from target sleep. You will not use the Godpower early on enemies. Until Turn 7 he haves only 3 creatures possible to play.

Maybe you are also lucky enough to copy one of his big creatures for late game.
