The End permanently exiles a problematic Mightform Harmonizer or Bristly Bill before it snowballs the board, denying any recursion. Elegy Acolyte is a strong lifelink blocker/racer against their creature-based landfall plan and can out-value their Llanowar Elves-fueled curve. Shoot the Sheriff actually works well here since none of their creatures are outlaws, but we trim copies since Dissection Practice's small pump/shrink rarely answers their bigger bodies like Mightform Harmonizer (4/4) or a doubled Mossborn Hydra. Keep the low curve to race before Earthbender Ascension and landfall triggers take over.
Duress strips their removal (Bitter Triumph), counterspells (We Say Thee Nay!), or key threats like Kaito before they can neutralize our aggression, which is vital in a mirror-ish black matchup where card advantage compounds. Elegy Acolyte is a strong lifelink body that both races and blocks their Floodpits Drowner, refueling our hand as combat damage lands. Corpses of the Lost is a slower enchantment that doesn't pressure planeswalkers like Kaito fast enough, and its Skeleton synergy is too narrow against a grindy, removal-heavy deck; Dissection Practice's small buffs rarely matter against a grindy 1-for-1 deck. Focus on curving out efficiently since they have as much or more removal than us.
Duress proactively strips their removal (Deadly Precision, Witherbloom Charm) before they can use it to swing combat math, which matters since this matchup is a race. The End permanently exiles a snowballing Magda, the Hoardmaster or Biotech Specialist, denying value engines rather than just trading. Corpses of the Lost is too slow against their efficient one and two-drops like Llanowar Elves and Gene Pollinator, and Dissection Practice's marginal pump rarely changes combat math against their bigger midrange bodies. Keep pressure high since they can go over the top with Magda's Dragon tokens in a longer game.
