This matchup is a race against a colorless-heavy artifact/creature ramp shell full of Eldrazi and Devourer of Destiny; Consign to Memory is excellent here since most of their threats are colorless. Rest in Peace shuts off graveyard synergies and any recursion while denying value engines. Ashiok, Dream Render stops their Urza's Saga and Sowing Mycospawn searches and exiles their graveyard resources. Spell Snare is weak since few of their spells cost exactly 2, and March/No More Lies are replaced by more impactful, proactive disruption against a grindy ramp deck.

Izzet Prowess runs key blue spells (Preordain, Expressive Iteration) so Mystical Dispute is a cheap, efficient counter to disrupt their setup. Prismatic Ending exiles their early Dragon's Rage Channeler or Slickshot Show-Off cleanly. Wrath of the Skies is often too slow and symmetrical against a low-curve aggro deck racing you, and Casey Jones is risky against their burn since discarding three cards at random can strand answers; trim both for proactive interaction. Keep Galvanic Discharge in as premier removal against their small creatures, while Consign to Memory can counter triggered abilities like prowess or colorless spells like Mishra's Bauble.

This is a mirror-adjacent matchup against another Phelia/Solitude/Quantum Riddler value deck packing Thoughtseize and Orcish Bowmasters. High Noon slows their blink/flicker value engine (Ephemerate, Flickerwisp) by limiting them to one spell per turn, which is painful against a deck that wants to chain cheap spells. Rest in Peace shuts off their Ephemerate rebound loops feeding the graveyard less directly, but mainly denies Overlord of the Balemurk's mill/return value and any graveyard recursion. Spell Snare is low-impact since few of their key spells cost exactly 2, and March of Otherworldly Light is replaced by more impactful disruption against their engine pieces.
