Mysterio then teamed up with Eddie Guerrero to win the WWE Tag Team Championship back from the Bashams at No Way Out. During this time Mysterio had a video camera, which was called the "619 cam", during his entrance he taped members of the audience with this. In a departure from traditional booking, the new champions did not defend their title at WrestleMania 21, but instead had a match against each other which Mysterio won. Two months later, at ECW One Night Stand, Mysterio faced and defeated long-time rival Psicosis for the first time in nearly five years.
