We have a great new tool for these decks against the white-based control decks. It has functionality against black as well.
Why is it great? Because we can sack cards like Rekindling Phoenix when they are about to get hit with Seal Away, Cast Out, Vraska’s Contempt or Settle the Wreckage. It can actually do a lot more than that. How about the synergy with Kari Zev, Skyship Raider? Just give Ragavan the boot at end of combat and that’s an extra card (sort of) for one mana. In a right deck, just sacking creatures from under a removal spell is just good as well.
