Death and Taxes relies heavily on Aether Vial and various Equipment like Meteor Sword and Pre-War Formalwear alongside a go-wide creature plan, making artifact and board-wipe answers valuable. Meltdown can wipe their Aether Vials and other cheap artifacts for two mana (X=1 plus {R}), while Ratchet Bomb scales to answer their wide boards of cheap creatures once set appropriately. Spell Pierce is weak since they play mostly creatures, which it cannot counter, and Into the Flood Maw only bounces one threat in a deck full of value creatures like Recruiter of the Guard that happily re-trigger when they re-enter. Keep Wasteland in since it punishes their reliance on Karakas and nonbasic lands.
