Dimir Tempo wins by protecting a single threat like Murktide Regent or Kaito with free countermagic, so Force of Negation lets you fight on their terms by pitching a blue card to stop a follow-up Thoughtseize, Force of Will, or a key threat on their turn. Consign to Memory is a cheap answer to Orcish Bowmasters triggers and can brick-wall their colorless spells like Mishra's Bauble, while its replicate cost scales well if you flood on mana from Ancient Tomb and Urza's Saga. Metallic Rebuke is a weaker counter here since it's easily played around once they know you're tapped low, and Sink into Stupor is too slow against a deck that rebuilds tempo with cantrips, so both come out. Keep the full artifact and land suite intact since Emry, Urza's Saga, and the Mox-fueled starts are your best way to out-pace their disruption before Murktide or Kaito lock the game up.

Izzet Delver's clock comes from Dragon's Rage Channeler and Murktide Regent, both of which die cleanly to Dismember's -5/-5. Consign to Memory handles their colorless Mishra's Bauble triggers and any colorless spells cheaply, fitting a low-curve mirror-ish race. We cut the card-selection Baubles and Metallic Rebuke since the 3-mana tax is too slow against a deck this fast, favoring hard removal and cheap free interaction instead. Play around their Daze and Force of Will by sequencing lands to keep mana up when possible.

Ocelot Pride Midrange is full of cheap one-and-two mana spells (Ocelot Pride, Guide of Souls, Swords to Plowshares, Static Prison), so Chalice of the Void set to one can lock out a huge portion of their deck while we operate off Ancient Tomb and artifact mana. Dismember is efficient removal for Ajani, Nacatl Pariah or Voice of Victory tokens before they snowball. We cut the slow card-selection Baubles and Metallic Rebuke, since tapping out for a 3-mana tax doesn't fit well against their proactive curve. Watch for Wasteland on our Ancient Tomb when sequencing Chalice.
