Dimir Tempo relies heavily on colorless cantrips like Mishra's Bauble plus Nethergoyf's escape and Murktide Regent's delve, making Consign to Memory excellent for countering their Bauble triggers and colorless spells, while Surgical Extraction strips a key escape or delve piece from their graveyard to blunt Nethergoyf or Murktide. Ratchet Bomb gives a clean answer to their small 1/1 Orcish Bowmasters tokens, Moonshadow once it's shrunk, or an early Tamiyo once flipped. We trim our own redundant cantrips (Mishra's Bauble, Preordain) since both decks are cantrip-heavy and card advantage matters less than disruption in this mirror-ish matchup, and cut the narrow Spell Pierce and Into the Flood Maw since Daze and Force of Will already cover countermagic and bounce is weak against their resilient threats. Keep the full Force of Will, Daze, and Dragon's Rage Channeler suite since protecting our own clock and contesting their disruption-heavy start is the core plan.
