This matchup is a race between two combo decks; Force of Negation is often uncastable for free since it isn't their turn when they combo off on theirs, so trim it for cheaper interaction. Consign to Memory counters colorless spells like Devourer of Destiny, Kozilek's Command, and their Eldrazi threats, which is exactly what this opponent is full of. Nihil Spellbomb strips their graveyard if they try to rebuy value with Kozilek's Command or block our own reanimation targets incidentally. Prismatic Ending is often too slow against their proactive mana ramp into giant Eldrazi, so shave a copy in favor of faster answers; keep Thoughtseize and Fatal Push as they attack their hand and Basking Broodscale/Glaring Fleshraker.

Izzet Prowess is a fast aggressive deck, so we want efficient interaction over reactive counterspells that ask us to hold up mana. Consign to Memory is excellent here as it counters Mishra's Bauble and triggered abilities, and its replicate cost lets us stop multiple triggers at once. Sheoldred's Edict forces a sacrifice which answers their best threat when they only have one creature, and Force of Negation is weak on our own turn against a tempo deck that doesn't telegraph a single big spell. Keep Solitude and Fatal Push as premium cheap removal against Dragon's Rage Channeler and Monastery Swiftspear.

Esper GenericBlink is a grindy, resource-rich mirror-like matchup full of value creatures like Overlord of the Balemurk and Witch Enchanter, so we want to attack their card advantage engines rather than durdle with card draw. Teferi, Time Raveler shuts off their instant-speed Ephemerate blink shenanigans and lets our own sorcery-speed removal go unanswered. Ashiok, Dream Render prevents their fetches from finding answers and mills them, which is relevant since they have no way to interact with a planeswalker easily. Consign to Memory answers their triggered abilities, while Faithful Mending is too slow in a matchup that comes down to threat density and disruption.
