4. Shawn Michaels vs. The Undertaker - WrestleMania XXVI
Which match was better, 25 or 26? Go watch them back-to-back, I don't know if one is "better" than the other it just felt like the final act of a play. Act 1 was their feud in the fall of 1997, Act 2 was WrestleMania 25 and the story came to its conclusion at WrestleMania 26. The matches just go together and the only reason I ranked 25 above it is because the ending wasn't quite as obvious since it didn't have the retirement stipulation. Although I considered putting it above 25 just for the jumping Tombstone!
3. Shawn Michaels vs. The Undertaker - WrestleMania XXV
HBK's tenth and final appearance on this list should show you why he's been dubbed "Mr. WrestleMania." Some might scoff at the idea of this match being so high, especially pushing out other classics on this list, but the bottom line is, the minute the three count was made in this match, it was one for the ages, it's the reason the term "instant classic" was coined.
