I love Obscura Confluence to make deals with other players. Just the other day I offered to help a player take out another player with it. Gave his creature Connive twice as well as a +2/2 and removed the ability of the opposing players only creature and made it a 1/1, this choice eventually lead me to winning the game. It was a neat way to use the card.
Reminder that Tivit's vote also happens on ETB. Using bounce spells, DeadEye Navigator, academy manufactor, time sieve. There are lots of ways to go infinite with Tivit. If you want a commander that can be politically minded and centers around a unique mechanic (voting) but can be built very competitively, Tivit is it.
