Mono-Green Landfall goes wide with cheap creatures like Llanowar Elves and Sazh's Chocobo, so countermagic that only stops one threat is less impactful than sweepers and removal. Strategic Betrayal is efficient one-for-one removal that also strips their graveyard, denying flashback value from Esper Origins. Pest Control wipes their cheap mana value 1 creatures like Llanowar Elves and Sazh's Chocobo. Keep Day of Judgment as your primary sweeper against their wide boards.

Dimir Midrange is full of efficient removal, card advantage, and disruption rather than cheap aggressive creatures, making your burn-based removal less impactful. Disdainful Stroke counters their mana value 4+ threats like Kaito, Bane of Nightmares. Spell Snare picks off their Bitter Triumph, Nowhere to Run, or Shoot the Sheriff at mana value 2. Strategic Betrayal forces them to exile a creature like Cecil, Dark Knight along with their graveyard. Keep Day of Judgment and Jeskai Revelation as your primary tools to stabilize and grind through their card advantage engines like Enduring Curiosity.

Dimir Excruciator is a durdly midrange-control deck full of discard, removal, and card advantage, so your narrow burn spells are weak while sweepers and disruption shine. Disdainful Stroke counters their expensive threats and sweepers like Superior Spider-Man or Deadly Cover-Up. Strategic Betrayal answers their few big threats like Superior Spider-Man or M.O.D.O.K. and hits their graveyard, denying recursive value. Duress strips their key noncreature spells like Stock Up or Deadly Cover-Up before they can generate value. Keep Day of Judgment and Jeskai Revelation as your primary path to stabilizing and out-grinding their card advantage.
