The best episode of all is the one where Sisko arranges Garrek to make a clip that makes it look like the Dominion is colluding with the Romulan's enemies (to make it so the Romulans don't join the side of the Dominion).
After handing it over to the Romulan, the Romulan examines it and calls it a fake. He says he is going to tell the Romulan government about his duplicitness, and when the shuttle leaves the station, it blows up. Sisko, enraged, confronts Garrek and Garrek, quite simply, tells Sisko that he told him that he could not create it well enough to fool the Romulans. However, now that it is damaged due to the explosion, the "flaws" will now have an explanation.
Sisko, at the end of the episode, basically says he can live with that. And then deletes the log. It was a unique episode as it showed our hero having a dark side, which was freaking awesome! The title was something like "Dancing In The Pale Moonlight" or something like that.
