The thing that determines you getting to SmackDown is how many Social Media Followers you have. The fastest way to get this would be to always select the Tune Up match option whenever given a choice. The higher star rating you get for the match, the more followers you gain. An easy way to get a 4-5 star match is to simply do your Signature move 2-3 times and your Finisher 2-3 times, and mixing up the moves you do to gain the momentum. You don't have to worry about letting your opponent beat on you every now and then for the Back and Forth points, since they could end up getting their own finisher and getting a surprise win.
