Death and Taxes runs many small, resilient white creatures like Stoneforge Mystic, Skyclave Apparition, and Recruiter of the Guard, and since they'll almost always control a Plains while you control a Swamp, Massacre is a free sweeper that answers their whole board at once. Surgical Extraction can proactively exile their Solitude or a key Equipment like a fetched item from Stoneforge Mystic once it hits the graveyard, denying rebuys. Daze loses value since they play a grindy, resource-based game rather than a pure tempo race, and Flow State is less impactful than direct removal against their go-wide creature plan. Kaito, Bane of Nightmares is safe from their Karakas, since he's only a creature (and hexproof) during your own turn, so Karakas can never legally target him.
