Winternight Stories is slow against a deck full of Thoughtseize and Duress, and Get Out is the weakest of your interaction here, so both come out. Bring in Abrade to kill Graveyard Trespasser, Badgermole Cub, and an animated Mutavault. Its 3 damage won't kill Sheoldred, the Apocalypse or the 6/6 Demon token from Unholy Annex/Ritual Chamber, so don't count on it for those. Negate counters noncreature spells such as Culling Ritual, Professor Dellian Fel, and Unholy Annex/Ritual Chamber. It can't stop a planeswalker's loyalty abilities once Dellian Fel is on the battlefield. Ashiok, Dream Render's -1 exiles their graveyard, which blanks graveyard plans like Takenuma, Abandoned Mire's channel ability. Keep Stubborn Denial and Prismari Charm in as your main interaction. Stubborn Denial counters noncreature spells like Thoughtseize, Fatal Push, Culling Ritual, and Professor Dellian Fel, but it can't hit creature spells. Prismari Charm can bounce Sheoldred, the Apocalypse or Badgermole Cub. Watch out for Thoughtseize and Duress stripping your interaction before you can deploy it.
