#4 Shawn Michaels costs Undertaker the World title (2010)
Two years after winning an opportunity to face the World Heavyweight Champion at WrestleMania inside the Elimination Chamber, the Undertaker defended the big gold belt in another one of those. Rey Mysterio, Chris Jericho, John Morrison, R-Truth and CM Punk were all up to the task of making this a memorable Chamber match. However, the main underlying story was Shawn Michaels and his desperation to fight the Deadman at WrestleMania, one year after their classic showdown at the Grandest Stage of Them All.
Despite suffering severe burns during his entrance, the gutsy Deadman was part of the final two with Chris Jericho. He looked all set to win and continue his reasonably long reign, but then out came Michaels. He had been hiding under the ring and came out through the outside steel, before hitting 'Taker with the Sweet Chin Music. In the process, HBK cost 'Taker the world title and gifted it to his old enemy, Chris Jericho. It was a great moment that lead to one of the most storied matches in WrestleMania history.
