I'm by no means an expert, but I would take a look at the Informer/Spy thread.
I did. I think its too linear of a formula. Doesn't allow that much versatility in case it gets disrupted. Plus if it gets caught with combo cards in hand its hard to get rid of them or cast them. Elvish Visionary can be cast to get a card then sac'd to dread return. Lab Maniac can be cast as well and I did it one game against MWS with grafdigger in play to win.
