Izzet Spellementals is entirely red and blue, making Flashfreeze a premium answer to their red spells like Prismari Charm, Traumatic Critique, and Hearth Elemental. Disdainful Stroke counters big threats like Eddymurk Crab, Hearth Elemental, and Sunderflock before they hit the field. Inevitable Defeat is efficient removal for their bigger threats like Hearth Elemental or Sunderflock. Cut slower value cards like Consult the Star Charts and the clunky North Wind Avatar in favor of proactive interaction, since this matchup is a race to disrupt their engine before it snowballs. Your Day of Judgment and Jeskai Revelation remain key stabilizers for the late game.

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.
