In January 2010, The Miz began a rivalry with MVP that began with a critically well-received verbal exchange between the two. The two met in an unadvertised match for the United States Championship at the Royal Rumble event with Miz retaining his title, but in the Royal Rumble match itself MVP eliminated both himself and The Miz. Also around this time, Miz formed a tag team with Big Show — later dubbed "ShoMiz" — and on the February 8 episode of "Raw" the two defeated D-Generation X and The Straight Edge Society to become the Unified WWE Tag Team Champions, making Miz the first wrestler in WWE history to hold three championships at the same time (United States, World Tag Team and WWE Tag Team Champion). At Elimination Chamber, Miz again successfully defended his United States Championship against MVP after interference from Big Show, ending their feud. At WrestleMania XXVI on March 28, ShoMiz defeated John Morrison and R-Truth to retain the title again. However, on the April 26 episode of "Raw", ShoMiz lost the championship to The Hart Dynasty (David Hart Smith and Tyson Kidd), and Big Show would attack Miz after the match, bringing an end to the team.
