The man with a 21-match winning streak at WrestleMania is going to show up quite often on this list. There is no denying that. And while Undertakers latter years were dedicated to having the best possible Mania match, some are just more must-see than others.Case in point, this is the first (second, if you count WM 17) epic showdown between Undertaker and Triple H, as the two members of the old guard threw haymakers at each other for the entire match until Taker managed to pull out the victory. It was a great match on its own, but it was easily outdone a year later.
