As I said elsewhere, I'll miss the channel lands but not much else. I spent the last few days of the old Standard playing some of my decks that I don't think will survive rotation, but I'm looking forward to making some new ones. I've lucked into opening three Darkstar Augurs so far and I definitely have plans for them.
Farewell is incredibly powerful, but it hasn't even been the white sweeper of choice for a while. I've been seeing Sunfall much more often. Wandering Emperor doesn't have any analogue to take its place, though, so it'll be interesting to see how its disappearance affects white control.
Overall... it's nice to see broken cards rotate out, but they printed some new broken cards to replace them, so... meh? I'm already eagerly anticipating the day next year when Sheoldred and Atraxa will depart. But there will still be plenty of newer nonsense then....
