Dimir Tempo's blue mana comes entirely from Islands (Island, Underground Sea, Undercity Sewers, plus the fetches that find them), and Daze needs an Island to return, so Choke puts real pressure on their Daze, Force of Will, Ponder, and Brainstorm mana once we're established. Pithing Needle stays in as a minor tool, for example naming Mishra's Bauble, since it only stops activated abilities that aren't mana abilities. Keep Wasteland and Ghost Quarter in to continue punishing their fetches and Underground Sea. Malevolent Rumble is a slight speed trim since this matchup rewards durable lock pieces over incremental card advantage.

Ocelot Pride Midrange presents small, aggressive bodies like Ocelot Pride, Guide of Souls, and Voice of Victory tokens that Dismember can efficiently remove for cheap, even late with life payments. Veil of Summer protects our Dark Depths/Thespian's Stage combo and other key permanents from their Thoughtseize and gives us a hexproof window against Orcish Bowmasters triggers tied to card draw. We trim some of our slower grindy pieces since this matchup is a race against their wide board and disruption. Karakas and Wasteland on their side are relevant, so keep our own Wasteland and Boseiju for mana disruption and artifact/enchantment hate against Static Prison.

Sultai Aluren leans on blue for Show and Tell, Ponder, Brainstorm, Stock Up, and Force of Will, so Choke can be a strong mana denial tool against their Islands (Island, Tropical Island, Hedge Maze, and the fetches that find them) once our lock is online. Veil of Summer makes our spells uncounterable for the turn, which blanks Force of Will, and gives us hexproof from their blue and black effects. It also draws a card if they have cast a blue or black spell that turn. Their own Veil of Summer is green, so it does not trigger ours. We keep one Disruptor Flute main rather than fully committing, since it can still tax Show and Tell or Aluren if drawn, but we trim copies for the more impactful anti-blue tools. Grafdigger's Cage does little here: Show and Tell and Omniscience put cards onto the battlefield or cast spells from hand, which Cage does not stop. It is not a priority in this matchup.
