No sideboard cards are available, so this configuration stays as-is. Izzet Spellementals leans on Eddymurk Crab and Hearth Elemental discounted by cheap cantrips like Opt and Sleight of Hand, so cheap, efficient removal is key — Firebending Lesson can kill Eddymurk Crab (5/5) or Hearth Elemental (4/5) outright if kicked for 5 damage, while Lightning Helix and Sear can weaken a Crab but won't finish it alone. Day of Judgment is strong if they've committed multiple threats, since none of their creatures dodge a sweeper. Keep Negate or No More Lies available for a game-ending Jeskai Revelation-style burst turn, though note this list doesn't actually run that card — their threats are creature-based, so prioritize removal over countermagic.

No sideboard cards are available, so this configuration stays as-is. Mono-Green Landfall uses Llanowar Elves for acceleration into Mightform Harmonizer and Icetill Explorer, with Ba Sing Se and Earthbender Ascension as long-game payoffs, so early removal on Llanowar Elves with Lightning Helix or Sear slows their whole curve. Day of Judgment is your best answer to a board that's gotten wide, since none of their common threats have inherent protection from destroy effects. Because this is a low-interaction creature deck, prioritize proactive card advantage from Stock Up and Jeskai Revelation to simply out-value them once the board is stabilized.

No sideboard cards are available, so this configuration stays as-is. Jeskai Control wants to grind with Tablet of Discovery, Stock Up, Jeskai Revelation, and Great Hall of the Biblioplex, so prioritize your own card advantage engines — Stock Up, Consult the Star Charts, and Jeskai Revelation — to keep pace. Use Day of Judgment to reset the board if they overextend with Thor, God of Thunder, and hold No More Lies or Negate for their Jeskai Revelation and Stock Up. Since Great Hall of the Biblioplex becomes a 2/4 Wizard mana sink in the late game, Sear can answer it once animated.
