This Eldrazi ramp-combo deck needs to chain Ancient Stirrings, Malevolent Rumble, and land drops into a big Emrakul or Devourer of Destiny turn, so High Noon slows their assembly significantly while we're comfortable playing one impactful spell per turn ourselves. Beza, the Bounding Spring stabilizes the life total and can generate a Treasure or extra bodies when we're behind on board against their oversized creatures. Avengers Disassembled's 3 damage sweep mode doesn't kill anything relevant here (their creatures are 2/2 or bigger and get bigger fast), so it comes out along with a spare Galvanic Discharge and Lightning Helix, which are too slow against 6/6s and 10/10s. Keep Field of Ruin and Demolition Field in to strip Eldrazi Temple and Urza's Saga, denying their colorless ramp.

Izzet Prowess relies on Mutagenic Growth, payable entirely with life for no mana spent, so Vexing Bauble counters it outright and disrupts their combat math and Dragon's Rage Channeler delirium plans. This is a low-land-count tempo deck, so our land destruction is largely dead and gets trimmed for more impactful sideboard cards. Rest in Peace also strips value from their Lava Dart flashback. Prioritize Wrath of the Skies and Erode to clear Dragon's Rage Channeler and Monastery Swiftspear before they accumulate too much prowess-fueled damage.

Esper GenericBlink leans heavily on Ephemerate looping Flickerwisp and Phelia, Exuberant Shepherd for repeated value, and Rest in Peace denies their graveyard-based recursion while shutting down their Overlord of the Balemurk and Emperor of Bones engines. High Noon is excellent against their multi-spell turns built around cheap enablers like Thoughtseize into Overlord of the Balemurk. This is a fair, land-light value deck, so our land destruction package underperforms and is cut for proactive disruption. Sequence carefully around their own Solitude and Prismatic Ending, which can answer our threats for free or cheaply.
