“Jeskai Control leverages a layered card advantage engine — cycling through Stock Up, Consult the Star Charts, and Tablet of Discovery in the early turns to hit land drops and find answers, while Jeskai Revelation serves as the primary mid-to-late game value engine that compounds card quality over time. The deck uses a suite of flexible, mostly-singleton removal spells (Pyroclasm, Day of Judgment, Fire Magic, Sear, Erode) and light countermagic (Negate, Three Steps Ahead, Flashback) to neutralize threats on a reactive basis, keeping opponents off-balance without committing to dedicated removal packages that can be stranded. Great Hall of the Biblioplex functions as a mana-sink win condition in long games, ensuring the control player never runs out of resources even when they've exhausted their spell-based draw.”

Buy sideboard on ManapoolMono Green Landfall is almost entirely green spells, making Flashfreeze a clean upgrade over No More Lies since it is a hard counter at the same mana cost, and a ramp deck full of Llanowar Elves and land-fetchers can easily pay No More Lies' {3} tax. Negate picks off their noncreature spells like Earthbender Ascension and Sapling Nursery, while Disdainful Stroke hits their expensive threats like Icetill Explorer, Mightform Harmonizer, and Sapling Nursery before they take over the board. Day of Judgment remains excellent against their go-wide landfall plan, so keep it in. Lightning Helix is a marginal cut since their creatures quickly outgrow 3 damage.
Dimir Midrange's biggest threats are Kaito, Enduring Curiosity, and Requiting Hex-fueled value engines that Get Lost answers permanently, including enchantments like Enduring Curiosity itself. Negate and Disdainful Stroke are strong against their removal and card draw spells like Bitter Triumph and Requiting Hex is too cheap to hit with Disdainful Stroke, but countering Kaito or Enduring Curiosity on the stack is high value. Firebending Lesson is a weak cut since their key threats (Kaito as a planeswalker, Enduring Curiosity) dodge damage-based removal while not a creature. Flashback is replaceable here since their graveyard isn't the main engine to punish.
BRG plays a steady stream of resilient creatures and value engines like The Sackville-Bagginses and Rottenmouth Viper. Strategic Betrayal makes them exile a creature of their own choice, so expect them to give up their weakest one, but it also exiles their whole graveyard, shutting off recursion from Lively Dirge. Get Lost is premium removal for Smaug the Magnificent or Umbral Collar Zealot, though it hands them two Map tokens, which can feed their sacrifice synergies. We trim some card selection since this matchup is more about surviving their threats than digging for answers, but keep the core engine intact. Day of Judgment remains crucial to reset the board against their wide creature counts, and Jeskai Revelation gives us 4 damage, a bounce, and card advantage in a longer game.
