The E&C Dynasty is a legendary tag team comprised of real-life childhood friends Adam Copeland and Jay Reso, better known to wrestling fans as Edge & Christian, respectively. The team won the WWF Tag Team titles seven times together, and then each man won tag titles with at least two other partners, i.e. Hulk Hogan (Edge), Lance Storm (Christian), Randy Orton (Edge), and Chris Jericho (both).
Although many successful tag teams have gone their separate ways, usually one man will have a far more successful singles career than the other, such as Bret Hart, Shawn Michaels, Davey Boy Smith, Booker T, Stone Cold Steve Austin, and even The Miz, to name a few. However, both Edge and Christian have had successful singles careers. Although it seemed like Edge's legacy would overshadow Christian's achievements, Christian balanced the scales significantly by winning the vacant World championship after Edge retired.
At this point, it is possible long-time rivals The Hardys could surpass them as the most successful tag team in both the tag division and the singles ranks, but it depends on how likely Matt Hardy is to succeed in TNA (and even then, it would probably be a minority opinion).
