The Confluence costs a massive six mana and three in colors, but you can goad one player's stuff three times, so it's Disrupt Decorum in a four player game, or you can use it as removal of a -3/-3 nature up to three times, which will kill indestructible stuff and not exile them so you can recur them later or you can Regrowth a sorcery/instant up to three times
Its a super simple commander, but I wish it had more powerful backgrounds to be paired with
Stunt Double can do anything from ambush attackers in combat to copying a legendary creature that's about to die anyway
Book cabs faster, track your rides, and manage city-to-city travel from one place
Personally, I want to combo it with Intruder Alarm and creatures that make tokens when you draw your second card, such as Emrakuls Messenger or Detective of the Month
