Dimir Tempo leans on Daze, Force of Will, and Thoughtseize to protect a resilient threat like Murktide Regent or flipped Tamiyo, so Lavinia, Azorius Renegade is excellent here — she taxes their noncreature spells and outright counters anything they try to cast for free, shutting off Daze and pitch Force of Will/Force of Negation. Pyroblast comes in to blow out their Brainstorm/Ponder/Daze/Force of Will on the draw or destroy a resolved Murktide Regent or Tamiyo, Inquisitive Student. Prismatic Ending is awkward since it can't hit anything with mana value greater than your colors spent and their key threats (Murktide, flipped Tamiyo) often dodge it cleanly, so it comes out, and Force of Negation is cut down since you're already loaded on proactive disruption and want bodies that pressure their clock. Keep Stifle in to blunt Wasteland and fetchland value, and keep Swords to Plowshares as your clean answer to Murktide Regent.

Ocelot Pride floods the board with small Cat tokens and Voice of Victory tokens, so Wrath of the Skies is excellent since it can be scaled to wipe their whole token board while sparing nothing bigger. Triumph of Saint Katherine is a lifelink body that stabilizes against their aggressive clock and dodges their small creatures in combat. Stifle has few profitable targets here (their tokens aren't triggered off abilities we can easily snipe), and Force of Negation is weaker against a deck full of creature spells and cheap noncreature threats it can't always catch profitably. Keep Swords to Plowshares and Prismatic Ending as premium answers to Ocelot Pride, Guide of Souls, and Ajani.

This is a mirror match against a very similar WU tempo shell, so Lavinia, Azorius Renegade is a strong one-sided effect that shuts off their free Daze and Force of Will while taxing their noncreature spells like Teferi, Time Raveler and Ponder. We bring in the extra Prismatic Ending copies since it cleanly answers their Teferi, Time Raveler and Tamiyo at low converge cost given our three-color-adjacent manabase. We trim our own Force of Negation since both decks are light on resolving explosive noncreature spells worth countering compared to just removing their threats, and cut one Consign to Memory since colorless spells are rare on their side. Keep Stifle in to counter Phelia attack triggers and fetchland cracks for tempo in this grindy mirror.
