I'm using this deck as well. As long as you don't brick initially, it is easy to get Ra out and the 9999 damage bonus. Now, if I can only get her to drop the 3rd princess. I stopped getting the other card drops as well. Nothing but gold boxes with gold I don't need.
And yeah, the deck still works fine unless you brick REALLY bad while Mai opens with a godly hand.
(Like what just happened to me....opened with no Aromage besides Jasmine and no Garden, while Mai opens with Harpie Queen, Hysteric Party, Joe, and the Harpie Lady that boosts ATK of WIND monsters.)
