Witch-king, Sky Scourge There's a lot of punishment dealt by the Witch-king, Sky Scourge
It can maybe be a sideboard card for red decks against slow decks

The whimsicott thing is the only non-prized based thing I can think of that allows this kind of deck to 1hitKO You see how manetric can pull off 120 damage in a heartbeat for two energy, and it has 170
