The classic deep advertising voice has nothing to do with effects. It is based on hiring a voice talent who has, in the industry parlance, "The Voice of God". Those who have that voice make hundreds of thousands of dollars a year, and are in great demand. If it could be achieved with an effect, everyone would be doing it, and the people with the talent would be out in the street.
If you follow along on the tutorial you posted, there isn't anything I can see that you can't do with Audition, short of the specific Maximizer plugin, which of course you can add, as a VST plugin to Audition, if you have 250 dollars to throw around. The only difference you'll find is that Audition doesn't have the skeuomorphic interface design you see with Reason. But if you walk your way through the tutorial, and apply similar settings in Audition, you can get very close. It's time to learn something about audio, and simply mimicking the settings shown in the tutorial is a good way to start.
