#2 World Heavyweight Championship Elimination Chamber (2011)
I still maintain to this day that 2011's Elimination Chamber pay-per-view was the strongest all-around instalment WWE has done to date, and SmackDown's Elimination Chamber match for the World Heavyweight Championship played a big part in that.
Of course, Edge retaining his title was never in doubt considering that the match between him and Alberto Del Rio was essentially already set in stone for WrestleMania 27, but the combatants of this contest did an exceptional job of making fans think the belt was indeed in jeopardy.
Edge and Rey Mysterio were the iron men of the matchup, lasting the entire time and Kane scored two eliminations before being ousted from the bout.
Edge and Mysterio had a long history with each other, so the fact that they delivered a fantastic final few minutes filled with suspenseful near falls and exhilarating action came as little surprise.
Christian returning afterwards to thwart Alberto Del Rio's attack on Edge was simply the icing on the cake.
