Oops! All Spells wins by casting Balustrade Spy or Undercity Informer to mill their entire library, then flashing back Dread Return to reanimate Thassa's Oracle — the whole sequence happens on one turn with ritual mana, so your primary goal is layering hate pieces that survive Force of Vigor. Deafening Silence is backbreaking here: limiting them to one noncreature spell per turn shuts off the Dark Ritual and Cabal Ritual chains needed to power out their combo, buying you the time to find additional disruption. Name Balustrade Spy or Undercity Informer with Disruptor Flute to tax the actual mill trigger; they will struggle to pay the extra three mana through Deafening Silence simultaneously. Grafdigger's Cage, Faerie Macabre, and Surgical Extraction back up the enchantment plan against the Narcomoeba/Dread Return axis, and your maindeck Thoughtseize lets you see their hand and rip the critical piece before they can go off. Wasteland, White Orchid Phantom, and Witch Enchanter are completely irrelevant against a landless deck, so cut them freely to maximize your density of interaction.
