Barrowgoyf is a resilient lifelinking, deathtouch threat that dodges Fatal Push and blocks Murktide Regent or Nethergoyf profitably while punishing their graveyard-fueled gameplan. Force of Negation lets us fight over their Tamiyo or Murktide for free on their turn, and Duress strips their Force of Will or Thoughtseize before we commit our own threats. Boomerang Basics is too slow against their proactive disruption, and with Barrowgoyf and Force of Negation raising our curve, we can trim a couple of Daze and Flow State since they don't advance our board against their own countermagic-heavy plan. Keep Thoughtseize and Force of Will in full to keep winning the disruption war.

Barrowgoyf's deathtouch lets it trade up with anything they build, including pumped Cat tokens or Ajani, Nacatl Pariah, while its lifelink helps against their aggressive clock. Engineered Explosives can be set to blow up their swarm of 1-mana threats like Ocelot Pride and Guide of Souls, or their 2-drops like Ajani and Amped Raptor, resetting their board. Brazen Borrower's Adventure bounces a problematic Ajani or Static Prison-locked permanent while the creature side blocks their ground threats in the air. Daze is weak since they aren't relying on tempo-sensitive spells we need to counter for free, and Boomerang Basics is replaced by more impactful sideboard tools.

Consign to Memory counters their colorless artifact spells and Karn, the Great Creator's triggered activations don't apply but note it can still hit colorless spells like The One Ring or Ugin, Eye of the Storms as they're cast. Engineered Explosives can wipe their small artifact tokens and cheap permanents once set appropriately, disrupting their Urza-lands artifact shell. Force of Negation is excellent to stop Show and Tell-adjacent blowouts like Karn, the Great Creator or Ugin, Eye of the Storms for free on their turn. Boomerang Basics and Flow State are too slow and low-impact against a proactive artifact combo-control deck, so we prioritize free interaction and targeted answers.
