This mirror-adjacent matchup is a race to assemble Tron and deploy threats, so a third Trinisphere further punishes their cheap interaction and Ancient Stirrings-fueled draws. Consign to Memory counters their colorless threats and is excellent against their Emrakul, the Promised End and its cast trigger. Giant's Boulder and Warping Wail are too slow and low-impact against their proactive curve. Keep Dismember count low since they have relatively few key small creatures worth killing outside Basking Broodscale.

Izzet Prowess wants to curve out with cheap creatures and burn spells, so Engineered Explosives set to 1 sweeps Dragon's Rage Channeler and Monastery Swiftspear while dodging their removal suite. Soulless Jailer's 0/4 body is a great blocker against their aggressive creatures and stops any Lava Dart flashback shenanigans. Trinisphere is weak here since it doesn't stop burn spells reaching your face and their curve is already efficient; Karn is less relevant since they don't rely on artifacts. Cursed Totem does not shut off prowess since prowess is a triggered ability, not an activated ability, so it does not affect their creatures and stays in the sideboard.

Esper GenericBlink leans on Flickerwisp, Phelia, Exuberant Shepherd, and Ephemerate for repeated value plus a Thoughtseize/Solitude disruption suite, so grinding resources matters more than tempo. Crucible of Worlds lets you rebuy Tron pieces or Eldrazi Temple after White Orchid Phantom strips them, keeping your engine online through their disruption. Trinisphere is weak since their curve isn't full of cheap spells you need to tax, and Cityscape Leveler gives you a huge trampling threat that survives their small removal suite.
