Endurance is excellent here, resetting their graveyard to shut off Nethergoyf/Murktide Regent delve fuel and can be evoked for free to blank a key turn while still being a real threat later. Sheoldred's Edict dodges Daze and Force of Will tax issues since it's an Instant that forces a sacrifice, cleanly answering a resolved Murktide Regent or planeswalker-mode Tamiyo/Kaito. Snuff Out is weak against their cheap, resilient threats and the deck has plenty of removal already, so it is the easiest cut along with the clunkier utility lands. Keep Thoughtseize and Wasteland in, since proactive disruption and mana denial are premium against their Wasteland/Daze tempo plan.

Sheoldred's Edict is great against Ocelot Pride's wide token board: you can make them sacrifice a creature token, or a nontoken creature, though they choose which one goes, so it is best when they have few creatures or when Fatal Push/Snuff Out whiff on bigger threats. Damping Sphere does not touch their lands, since Plateau, Sunbaked Canyon and their other lands each tap for one mana. Its value here is the tax on each additional spell a player casts in a turn, which punishes their cheap multi-spell turns of Ocelot Pride, Guide of Souls and Swords to Plowshares. It taxes us too, and it mainly buys time rather than answering threats outright. Snuff Out is a weaker cut since many of their key threats (Ocelot Pride, Guide of Souls) are already handled by Fatal Push, and utility lands like Bojuka Bog and Talon Gates of Madara are the least impactful mainboard cards against their proactive aggro-midrange plan. Keep Thoughtseize and Orcish Bowmasters in, since disrupting their hand and punishing their card draw remains central to winning the race.

Collector Ouphe doesn't stop Aluren itself (an enchantment, not an artifact), but it shuts off Lotus Petal. City of Traitors and Ancient Tomb are lands, so their mana is unaffected. It's a modest hit on their acceleration, and it doubles as a real clock. Force of Vigor is premium removal for Aluren and Omniscience (it can also hit Lotus Petal), and it can be cast for free by exiling a green card from hand on the opponent's turn to blow up their engine. Endurance is a flash 3/4 reach body that blocks well and applies a clock. Fatal Push and Snuff Out are mostly weak against their plan: Atraxa, Grand Unifier has mana value 7 and dodges Fatal Push, and both Atraxa and Acererak the Archlich are black, so Snuff Out can't target them. That makes them the first cuts alongside the narrower utility lands.
