Mono-Green Landfall grinds you out with Icetill Explorer, Mightform Harmonizer, and Earthbender Ascension scaling huge creatures, so Pyroclasm helps clean up their small early creatures like Llanowar Elves and Sazh's Chocobo before they snowball. Full Bore adds a pump option to push aggression. Soul-Guide Lantern is mostly a sideboard hedge against Esper Origins' flashback and graveyard shenanigans. Keep the low-impact pump spells trimmed since this matchup is more about racing than combat tricks.

Dimir Midrange leans on a heavy removal and disruption suite (Bitter Triumph, Requiting Hex, We Say Thee Nay!, Nowhere to Run) so protecting your threats matters more than pump spells that just get two-for-one'd. Secret Identity and Shore Up give your key creatures hexproof to dodge removal like Bitter Triumph and Requiting Hex, though note Nowhere to Run specifically lets them target your creatures as though they didn't have hexproof, so it still gets through. Spell Pierce punishes their proactive noncreature plays like Kaito, Bane of Nightmares. Cut the weaker pump effects that don't survive their removal-heavy game plan.

Dimir Excruciator's plan revolves around discard (Duress), removal (Requiting Hex, Bitter Triumph), and a grindy Doomsday Excruciator/Day of Black Sun late game, so keeping your threats alive with Secret Identity and Shore Up is key to closing the game before they stabilize. Spell Pierce punishes their cheap disruption spells when they're tapped out on turns 2-3. We trim slower pump effects that don't help you race their removal-heavy plan.
