7. Triple H
The King of Kings, The Game - Triple H has already faced Undertaker thrice. However, he hasn't defeated the Phenom even once. However, this could be the Undertaker's final match, and final matches are always breath-taking to watch. But, the Undertaker needs a sturdy opponent to wrestle against, and provide a five star show with, and that superstar is none other than Triple H. A match with the Undertaker could be excellent for both the parties, and it could be a great send off for the Undertaker. Triple H and the Undertaker always have great matches, and WM 30 will be no exception. Hopefully, the WWE takes this into notice and this match happens, for the benefit of everyone!
