Jeskai Control aims to answer your threats one-for-one with Lightning Helix, Get Lost, and No More Lies while building to sweepers like Day of Judgment and card advantage engines like Consult the Star Charts and Stock Up. Duress comes in to strip counterspells and sweepers before you commit to the board, giving your threats a clear path to connect. Intimidation Tactics helps push through the evasion-light control gameplan, letting your creatures attack past blockers like North Wind Avatar or Beza, the Bounding Spring. Bitter Triumph and Requiting Hex are reactive removal spells that are less impactful in a matchup where the opponent's threats are few and arrive late, making them the natural cut. Your aggressive curve of Flamewake Phoenix, Bloodthorn Flail, and Marauding Mako applies the pressure needed to close before their late-game card advantage takes over.
UR Aggro is a tempo-oriented deck that wants to ride early threats to victory while protecting them with cantrips and countermagic. Pyroclasm is your best answer, wiping their board of small creatures before they can snowball an advantage. Molten Collapse gives you flexible interaction against their creatures and small noncreature permanents. Bloodghast and Winternight Stories are too slow for this matchup, and one copy of Monument to Endurance and Bitter Triumph come out as well since your priority is staying alive through early aggression rather than generating long-game value.
Weenie White floods the board with cheap fliers like Momo, Friendly Flier and Sage of the Skies backed by Haliya, Guided by Light, so your priority post-board is mass removal and disruption. Pyroclasm clears their early board before Haliya can generate too much value, and Molten Collapse handles problem permanents like Springleaf Drum or Virtue of Loyalty that accelerate their gameplan. Intimidation Tactics can neutralize their best attacker in a crucial combat step, buying time for your Flamewake Phoenix and Marauding Mako to close the game. Requiting Hex is too slow and situational against their low-curve threat density, and Monument to Endurance and Winternight Stories are too passive when you need to be trading resources early.
