Dimir Tempo aims to sculpt the perfect hand with Brainstorm and Ponder while deploying efficient threats like Murktide Regent and Nethergoyf backed by Force of Will and Daze, so your primary goal is to land Aether Vial early to play around their counterspells and strip their key pieces with Thoughtseize before they can operate. Disruptor Flute naming Instant is the standout post-board tool here — it taxes Force of Will, Daze, Brainstorm, Fatal Push, and Snuff Out by two mana each, effectively strangling their tempo gameplan and making it nearly impossible for them to counter your threats while advancing their own board. Faerie Macabre provides free, uncounterable graveyard disruption that can exile blue cards to slow Murktide Regent or strip Nethergoyf's graveyard fuel, while Surgical Extraction pairs with your Thoughtseize discard effects to permanently remove a key card like Murktide or Tamiyo, Inquisitive Student. Wasteland backed by White Orchid Phantom is a powerful mana denial axis since they lean heavily on Underground Sea, so prioritize attacking their blue mana to strand Force of Will in hand. Post-board they will bring in Toxic Deluge and Sheoldred's Edict for your creatures, so keep Stoneforge Mystic equipment live and be willing to spread your threats across multiple turns rather than over-committing.
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.
Sneak and Show is a pure combo deck racing to resolve Show and Tell or Sneak Attack to put Emrakul, the Aeons Torn or Atraxa, Grand Unifier into play off fast mana like Ancient Tomb and Lotus Petal. Deafening Silence is your best post-board weapon — it prevents them from chaining cantrips into a same-turn combo, forcing them to slow down dramatically. Disruptor Flute should name Show and Tell on the play or whichever piece Thoughtseize doesn't strip; use Thoughtseize aggressively to identify which win condition they're on before naming. Note that Emrakul has protection from colored spells, so Karakas is your primary answer to a resolved Emrakul — activate it before damage to return it to their hand — while Swords to Plowshares and Solitude cleanly answer Atraxa; Skyclave Apparition can also exile a resolved Sneak Attack since its mana value is exactly 4.
