I could see that working well. Honestly the fact that Modern horizons 3 just came out did drive me to add some newer cards to help with the list being more relevant. But if I did an update that didn't follow a new set I would likely run Karn and some goodies in the board.

how do you feel about running a karn, the great creator with some utility in the sideboard in this?
