Ocelot Pride Midrange goes wide with cheap Cat tokens and applies fast pressure, so Fatal Push is efficient, cheap removal for their small creatures and Ajani tokens. Barrowgoyf blocks well, gains life via lifelink, and serves as a strong alternate win condition if Doomsday gets disrupted by their Thoughtseize and Orcish Bowmasters. Murktide Regent is too slow and mana-hungry against their aggressive clock, and Daze/Lotus Petal are weak against their Wasteland-heavy manabase.
Dimir Tempo's Force of Will, Daze, and Wasteland make resolving Doomsday hard, so Force of Negation lets you fight through their disruption on their turn, though it cannot protect your own combo turn for free. Barrowgoyf is a resilient, disruption-proof clock that punishes their graveyard-heavy plan and gives you a backup win condition when combo gets too contested. Daze is weak once you're tapped out going for the kill and Lotus Petal is a liability into Wasteland-heavy mana denial, so trim both slightly.
Sultai Aluren wants to resolve Show and Tell into Omniscience or Atraxa, Grand Unifier, or assemble the Aluren engine, so Force of Negation is a free answer that can strip their payoff before it lands. Barrowgoyf provides a proactive clock that punishes their graveyard-filling Stock Up and Ponder engine and doesn't care about their Force of Will-heavy protection suite once it's on the battlefield. Daze and Lotus Petal are trimmed since they're low-impact against a deck built to disrupt or outrace fast starts.
