This matchup is a race against Basking Broodscale value engines and giant Eldrazi threats like Emrakul, the Promised End and Devourer of Destiny. Wrath of the Skies is excellent since it can be tuned to wipe their small Eldrazi Spawn tokens and Basking Broodscale while leaving your bigger threats, or scaled up against a wider board. Obsidian Charmaw comes in as an efficient flier that also blows up Eldrazi Temple, Ugin's Labyrinth, or Urza's Saga to cripple their colorless mana base. Lightning Bolt and Stubborn Denial are weak here since their threats are large and resilient, and countermagic is less impactful against a deck full of card advantage engines rather than must-answer spells.

Izzet Prowess is full of blue spells like Preordain and Expressive Iteration, making Mystical Dispute a cheap, efficient counter that often costs just {U}. The extra Consign to Memory helps stop Cori-Steel Cutter triggers and colorless value like Mishra's Bauble. Prismatic Ending easily exiles most of their threats (Dragon's Rage Channeler, Monastery Swiftspear, Slickshot Show-Off) since cheap one- and two-drops are readily answered by converge, but being sorcery speed is awkward against haste, so cutting two copies provides flexibility. Stubborn Denial is cut since Ferocious is unreliable early and paying {1} is trivial for an aggressive deck that wants to race.

Esper GenericBlink leans on value creatures like Orcish Bowmasters, Solitude, and Overlord of the Balemurk alongside blink effects like Ephemerate and Flickerwisp, while Wrath of the Skies can be set low to clear their cheap threats efficiently. Consign to Memory stops their triggered abilities on entry (enters-the-battlefield triggers from creatures blinked by Ephemerate, Overlord of the Balemurk mill triggers). Lightning Bolt struggles to profitably trade with their bigger threats and Prismatic Ending is less needed since Wrath does that work at sweeper scale; keeping some removal is fine, but this swap maximizes sweeper coverage against their go-wide value plan.
